<title>DESCRIPTION</title>
<para>Semantic Delivery Language (SDL) is defined by a Standard Generalized
Markup Language (SGML) document type description (DTD). The language uses
generalized presentation-oriented markup and excludes typical SGML features
that may prevent performance-oriented, on-line delivery systems from using
the language.</para>

<title>DESCRIPTION</title>
<para>The virtual page ( <literal>virpage</literal>) element is the smallest,
directly addressable unit in a document. It corresponds to a topic. Ideally,
documents presented on-line (and perhaps even on paper) should be organized
into small topics that are complete unto themselves. This allows readers to
find and access the desired information.</para>
<para>A virtual page contains all information necessary to establish a formatting
context. Virtual pages may be displayed and understood when removed from
the context of the document as long as the table of semantics and styles
( <literal>toss</literal>) element is available for formatting information.
</para>
<para>A virtual page may have zero or more <literal>head</literal> elements
that provide title information and may also be used in display decoration,
such as a title bar. The first <literal>head</literal> of a virtual page is
intended to be displayed in a table of contents for the document.</para>
<para>Following the <literal>head</literal> elements is an optional system
notation block ( <literal>snb</literal>). The system notation block, which
provides access to objects external to the document, is covered later in this
document.</para>
<para>Finally, a virtual page may contain any combination of <literal>block</literal> or <literal>form</literal> elements, including none.</para>
<para>The attributes of <literal>virpage</literal> are:</para>

<title>DESCRIPTION</title>
<para>The system notation block ( <literal>snb</literal>) provides a container
for elements that access data that are not in SGML notation. The one exception
to this rule is the <literal>text</literal> element. The <literal>text</literal>
element is in the system notation block because it is intended for use as
a rich text alternative to other elements in the <literal>snb</literal> when
elements are tried in turn during the instantiation of a system notation reference
( <literal>snref</literal>) looking for an alternative that can be formatted
on the current system.</para>
<para>Data in the system notation block are not intended to be presented to
the reader in the order that they appear in the document. The structural
position of each <literal>snb</literal> element is established by a system
notation reference.</para>
<para>Collecting all elements that require system resources at the top of
the virtual page allows an application to marshal these resources before they
are referenced. This gives the application the ability to alter the presentation
of both the element and its reference based on the availability and performance
of the required system resources.</para>
<para>The optional <literal>head</literal> element may be used by an application
when presenting a list of required resources for a document.</para>

<title>DESCRIPTION</title>
<para>Blocks are the basic unit of display style. All data within a block
are rendered in the style of the block that contains them. Blocks may contain
zero or more <literal>head</literal> elements followed by zero or more paragraphs
( <literal>p</literal>) or character paragraphs ( <literal>cp</literal>).
</para>
<para>Structurally, blocks contain a set of logically related paragraphs.
A block identifies a display chunk, not document hierarchy elements. Blocks
have an inherently flat structure; blocks do not nest. The presentational
effect of nested blocks can be achieved by using the <symbol role="Variable">level</symbol> attribute.</para>
<para>The structure of a document includes blocks that are part of the principal
view and, optionally, blocks that form an alternate view. The principle view
makes the assumption that primary blocks are presented in order as the sequential
content of the document. That is, when taken in order the primary blocks compose
the principle view of the document. For the purpose of this language, the
principle view is the same as the traditional, printed view.</para>
<para>An alternate block is asynchronous to the primary document order. Alternate
blocks may represent traditional, asynchronous elements such as a footnote
or a spread, or some additional documentation (a teacher's section of a combined
teacher/student manual, for example.) Alternate content blocks should only
be included in the primary content by reference.</para>
<para>The <symbol role="Variable">level</symbol>, <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of a <literal>block</literal> can be used to look up formatting and semantic information in the
table of semantics and styles ( <literal>toss</literal>) element (covered
later in this document).</para>

<title>DESCRIPTION</title>
<para>The <literal>form</literal> element is a generalized representation
of a data element that is partially preformatted. The <literal>form</literal>
element is designed to be rendered in real time and automatically derived
from typical SGML table markup. Uses include tables, lists and labeled lists.
Generally, a <literal>form</literal> may be used to represent any information
that is layout sensitive or contains data to be presented in a two dimensional
matrix.</para>
<para>A <literal>form</literal> is made up of zero or more <literal>head</literal>
elements followed either by a form style ( <literal>fstyle</literal>) and
the form data ( <literal>fdata</literal>) or the form data followed by the
form style.</para>

<title>DESCRIPTION</title>
<para>The reference row vector ( <literal>frowvec</literal>) describes the
style of a row in a <literal>form</literal> and contains pointers (id references)
to the contents of the row. There must be a row vector per row in the <literal>form</literal>.</para>
<para>The <emphasis>hdr</emphasis> attribute designates the entire row as
a head row. Heads are significant because a display program might need to
manage the display of heads differently than it does the data matrix. This
is particularly true if the <literal>form</literal> must scroll, covers multiple
screens or is displayed as a graph.</para>

<para>Within a <literal>form</literal> element, spanning of rows or columns
is done by repeating the appropriate id reference in the <emphasis>cells</emphasis>
attribute of the <literal>frowvec</literal>. If the data is to be repeated
in multiple unspanned cells, the <literal>block</literal> must be repeated
and assigned unique identifiers.</para>
<para>The length of a row is the length of the cells in that row; the width
is the cumulative width of each cell in that row. Row length may be determined
at or before runtime. Typically, the length of a row is the length of the
longest <literal>block</literal> or <literal>form</literal> in the row. There
are two exceptions to this rule: the blocks or forms in the row can have
an assigned length, or the id reference could be to an element that is not
in the data container. These exceptional cells are referred to as virtual
cells; virtual cells do not affect the length of the row.</para>
<para>Virtual cells may contain more data than can be displayed in the area
assigned. Examples include blocks with the length set that contain long paragraphs,
forms or figures. The actual display area of a virtual cell can be thought
of as a viewport onto the data of a cell. Alternatively, virtual cells can
use an information hiding technique such as an icon leading to a separate
window.</para>
<para>The id references in a reference row may specify elements that are not
in the data container of its <literal>form</literal>, even if the elements
are not physically close. To protect the performance of the <literal>form</literal> element, references to data outside the current <literal>form</literal> may also be handled as virtual cells. The display program may
take the liberty to replace any information referenced in a row vector that
does not belong to the current <literal>form</literal>'s data element with
a link or icon.</para>

<title>DESCRIPTION</title>
<para>Paragraphs identify a formatting unit. Paragraphs collect information
that needs to be rendered contiguously within a region. Paragraphs inherit
style from their containing <literal>block</literal> although adjustments
can be made by using the <symbol role="Variable">class</symbol> and
<symbol role="Variable">level</symbol> attributes of the enclosing <literal>block</literal> plus the <emphasis>ssi</emphasis> attribute of the <literal>p</literal>
to effect a lookup in the table of semantics and styles ( <literal>toss</literal>)
element (covered later in this document).</para>
<para>Paragraphs may contain text, references and <literal>key</literal> phrases.
The <literal>key</literal> element (discussed later in this document) may
modify the style of a portion of a paragraph but the modification is always
restricted to the current paragraph.</para>

<para>Character paragraphs are similar to paragraphs. The only difference
is that markup contained in the text of a character paragraph is ignored.
The only markup not ignored is the ``&lt;/'' character pair. If that pair

<para>Heads are phrase-like elements that are associated with the entire section
that contains it. Heads may contain zero or more <literal>subhead</literal>
elements followed by zero or more paragraphs.</para>
<para>The <literal>head</literal> element may also be used as the caption
of a graphic (covered later in this document).</para>
<para>The user-defined head ( <literal>udefhead</literal>) value is for use
by the developer of a higher level DTD to SDL translator when an unexpected
use for a <literal>head</literal> is found.</para>

<title>DESCRIPTION</title>
<para>A <literal>link</literal> element is the start point of a hyperlink
to another spot in the document or, via the system notation block ( <literal>snb</literal>), to another document or active hyperlink. The active hyperlinks
are <literal>sys-cmd</literal> and <literal>callback</literal>. These hyperlinks
(covered later in this document) are used to execute an operating system command
or to initiate a callback to the application respectively.</para>
<para>A <literal>link</literal> may surround any text in the document, including
text found in paragraphs or heads, with the only exception being that <literal>link</literal> elements may not contain other <literal>link</literal> elements.

<title>DESCRIPTION</title>
<para>Key phrases are data that are key to understanding the paragraph in
which they exist; that is, they have a special significance. The <literal>key</literal> element is used to call readers' attention to a particular phrase.
The <literal>key</literal> element exists only within the context of a paragraph
( <literal>p</literal>); it is document sub-structure.</para>
<para>The semantics of the <literal>key</literal> element have value to both
rendering and navigation. When rendered, the phrase is highlighted, typically
using a different font style or attribute. In navigation, <literal>key</literal>
data can be used as fields in semantic searches or as variables in a relevance-ranking
algorithm.</para>
<para>There are an infinite variety of key phrases possible in source documents.
To assure that the delivery system can fully use the semantics of <literal>key</literal> data, this delivery format forces the semantic to be normalized.
Each phrase is required to have a <symbol role="Variable">class</symbol> attribute
as well as an optional source semantic identifier ( <emphasis>ssi</emphasis>).

<title>DESCRIPTION</title>
<para>The <literal>spc</literal> element allows special characters, that is,
those not in the current font, to be included in text. This is often achieved
in DTDs by the use of character entities. SDL avoids runtime evaluation of
entities because entities are global to a document and, for performance reasons,
SDL applications often do not wish to process all global information just
to display a single topic.</para>

<title>DESCRIPTION</title>
<para>The <literal>graphic</literal> element allows incorporation of graphic
images into an SDL-conforming document. Only one graphic type element is declared;
the <symbol role="Variable">class</symbol> attribute is used to distinguish
between figure, in-line or button. A graphic image is incorporated by putting
an <literal>snref</literal> element in the document at the point of inclusion.
The <emphasis>rid</emphasis> attribute of the <literal>snref</literal> should
refer to the <literal>graphic</literal> element describing the storage location
and format of the image.</para>
<para>The attributes of <literal>graphic</literal> are:</para>

<title>DESCRIPTION</title>
<para>The <literal>script</literal> element is the mechanism within SDL for
collecting usage data or generating dynamic (on-the-fly) text. When referenced
via an <literal>snref</literal>, the CDATA content of the <literal>script</literal> element is passed to the designated interpreter. If the return
value from the interpreter is non- <symbol role="Define">NULL</symbol>, that
value is interpolated into the document at the point of the <literal>snref</literal>. If the designated interpreter is embedded in the application,
global variables may be used to collect usage data; otherwise, some mechanism,
such as temporary files, may be used.</para>

<title>DESCRIPTION</title>
<para>The <literal>switch</literal> element is part of the system notation
block, <literal>snb</literal>, and is always instantiated via a reference
by a <literal>link</literal> element. When activated by the hyperlink, the
interpreter ( <emphasis>interp</emphasis>) is called passing it the CDATA
content of the switch and the interpreter returns a non-negative number. The
return value of the interpreter is used to index into the list of <emphasis>branches</emphasis> and the hyperlink is continued to that ID. A return value
that is non-numeric, less than zero or greater than the number minus one of
the <emphasis>id</emphasis>s in the <emphasis>branches</emphasis> attribute,
will cause the hyperlink to continue to the first <emphasis>branch</emphasis>
in the list.</para>

<title>DESCRIPTION</title>
<para>The <literal>loids</literal> element is a container for a list of identifiers
in the document. The list appears in the order the identifiers appear.</para>
<para>The <literal>loids</literal> element can be used to generate a table
of contents for the document by selecting only those elements whose
<symbol role="Variable">type</symbol> is <literal>virpage</literal> and listing the
heads of those <literal>virpage</literal> elements. The <emphasis>rlevel</emphasis>
attribute can be used to infer the nesting level of the <literal>virpage</literal>
and to avoid reading the <literal>head</literal> of virtual pages whose nesting
<symbol role="Variable">level</symbol> is deeper than is currently being displayed.

<para>The list of phrases ( <literal>lophrases</literal>) element is generated
by the higher level DTD to SDL translator. It is a list of phrases used from
the <literal>toss</literal> element (covered later in this document) contained
in this document. The phrases are used to map the user's knowledge domain
into the constructs used in SDL. This information can be used to pass the
phrases available for structured or semantic searches to a browser or viewer
to allow that browser or viewer to offer that information to the user.</para>
<para>The <literal>lophrases</literal> element differs from the phrases in
the <literal>toss</literal> in that the <literal>toss</literal> contains all

<title>DESCRIPTION</title>
<para>The <literal>toss</literal> element is a container for the table of
semantics and styles. Each sub-element of the <literal>toss</literal> represents
a different formatting group. These sub-elements also contain <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> (source semantic identifier) attributes
to allow general and specific semantic or structured searches. A <emphasis>phrase</emphasis> attribute of many of the <literal>toss</literal> sub-elements
also assists by providing a natural language phrase to describe the semantics
of the element as used in the higher level DTD to SDL translation.</para>
<para>Lookups in the <literal>toss</literal> are done by matching the
<symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of
the element in the document proper with the <symbol role="Variable">class</symbol>
and <emphasis>ssi</emphasis> attributes of the sub-element of the <literal>toss</literal>. The lookup can often be further refined by matching the
<symbol role="Variable">level</symbol> attribute (if present) of the element in the

<title>DESCRIPTION</title>
<para>The <literal>keystyle</literal> element provides semantic and font information
for <literal>key</literal> phrases in the document.</para>
<para>When a <literal>key</literal> element is encountered in the document,
the <literal>toss</literal> list of <literal>keystyle</literal> elements is
ssearched with an attempt made to match the <symbol role="Variable">class</symbol>
and <emphasis>ssi</emphasis> (if any) attributes of the <literal>key</literal> element to the <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> (if any) attributes of the <literal>keystyle</literal>. If
the <literal>keystyle</literal> specifies an <emphasis>rlevel</emphasis> attribute,
the search is further refined by matching the <symbol role="Variable">level</symbol>
of the <literal>block</literal> containing the paragraph ( <literal>p</literal>) to the <emphasis>rlevel</emphasis> of the <literal>keystyle</literal>.
If the <literal>key</literal> element has no <emphasis>ssi</emphasis> attribute,
the search in the <literal>toss</literal> looks for a <literal>keystyle</literal>
element with no <emphasis>ssi</emphasis> specified. A <literal>keystyle</literal>
element with no <emphasis>ssi</emphasis> specified matches any <emphasis>ssi</emphasis> in a <literal>key</literal> element although an explicit <symbol role="Variable">class</symbol>/<emphasis>ssi</emphasis> pair is chosen in
preference.</para>
<para>When a match is found, the font information contained in the <literal>keystyle</literal> is used in formatting the <literal>key</literal> element.
</para>
<para>The attributes of <literal>keystyle</literal> are:</para>

<title>DESCRIPTION</title>
<para>The <literal>headstyle</literal> element provides semantic, font and
formatting information for headings ( <literal>head</literal> and <literal>subhead</literal>) in the document.</para>
<para>When a heading is encountered in the document and that heading has an <emphasis>ssi</emphasis> attribute, the <literal>toss</literal> list of <literal>headstyle</literal> elements is searched with an attempt made to match the
<symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of
the heading to the <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of the <literal>headstyle</literal>. If the <literal>headstyle</literal> specifies an <emphasis>rlevel</emphasis> attribute, the
search is further refined by matching the <symbol role="Variable">level</symbol>
of the element containing the heading to the <emphasis>rlevel</emphasis>
of the <literal>headstyle</literal>. If the element containing the heading
does not have a <symbol role="Variable">level</symbol> attribute, the
<symbol role="Variable">level</symbol> of its containing element is used, and so on.
A <literal>headstyle</literal> element with no <emphasis>ssi</emphasis> specified
matches any <emphasis>ssi</emphasis> in a <literal>head</literal> element
although an explicit <symbol role="Variable">class</symbol>/<emphasis>ssi</emphasis> pair is chosen in preference.</para>
<para>When a match is found, the font and style information contained in the <literal>headstyle</literal> is used in formatting the heading.</para>
<para>The attributes of <literal>headstyle</literal> are:</para>

<title>DESCRIPTION</title>
<para>The <literal>formstyle</literal> element provides semantic, font and
formatting information for <literal>form</literal> elements.</para>
<para>When a <literal>form</literal> element is encountered in the document
and that element has an <emphasis>ssi</emphasis> attribute, the <literal>toss</literal> list of <literal>formstyle</literal> elements is searched with
an attempt made to match the <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of the element to the <symbol role="Variable">class</symbol>
and <emphasis>ssi</emphasis> attributes of the <literal>formstyle</literal>. If the <literal>formstyle</literal> specifies an <emphasis>rlevel</emphasis> attribute, the search is further refined by matching the nesting
<symbol role="Variable">level</symbol> of the <literal>form</literal> to the <emphasis>rlevel</emphasis> of the <literal>formstyle</literal>. A <literal>formstyle</literal> element with no <emphasis>ssi</emphasis> specified, matches any <emphasis>ssi</emphasis> in a <literal>form</literal>, although an explicit
<symbol role="Variable">class</symbol>/<emphasis>ssi</emphasis> pair is chosen in
preference.</para>
<para>When a match is found, the font and style information contained in the <literal>formstyle</literal> is used in formatting the element.</para>
<para>The attributes of <literal>formstyle</literal> are:</para>

<entry align="left" valign="top">Column widths. One specification for each
column in the <literal>form</literal>. Amounts given for each column  are
summed and each column is then given a  fraction of the available formatting
space equal to  its specification divided by the total. Specifications take
the form D[,T[,G]] where ``D'' is the  desired (optimal) column width, ``T''
is the  amount the column is willing to grow (take) and,  if ``G'' is unspecified,
willing to give (that is, plus  or minus). ``G'' is the amount the column
is willing to shrink (give). Column specifications are delimited by a space.
For example, a specification of: COLW=``10 90'' implies two columns with the
first taking 10% of  the available space and the second taking 90%. If either
column has a graphic or unsplittable word  that pushes it over the size specified,
a horizontal  scrollbar is added and the available space is  grown until the
requirement can be met. A specification of: COLW=``20,5 80,5'' implies two
columns with the first optimally taking 20% and the second optimally taking
80%. Each column, however is willing to shrink or  grow such that the ranges
of sizes run from 15/85  to 25/75. If the sizes cannot be adjusted to contain
a graphic or unsplittable word, a horizontal scrollbar is  added and the available
space is grown until the requirement is met. Finally, a specification of:
COLW=``20,10,5 80,5,10'' implies two columns with the first optimally taking
20% of the available space but willing to take  as much as 30% or a little
as 15%. The second  column desires 80% but is willing to take as  much as
85% or as little as 70% of the available  space. A scrollbar may be added
to  the viewed space if the constraints cannot be met. The specifications
need not all be uniformly singles, doubles or triples. That is, a legal specification
could take the form: COLW=``20,5 80,0,5'' that translates to two columns;
the first  desiring 20% of the available space but willing to  take as much
as 25% or as little as 15/80  (18.75%). The second column desires 80% of the
 available space, but is willing to take as little as  75%. The totals in
the above examples usually  add up to 100. This value is mere convention for
 ease of use. In practice, the sum of desired points  may be any number. If
the number of columns specified is greater than  the <emphasis>ncols</emphasis>
attribute of the <literal>fstyle</literal> of the related  <literal>form</literal>,
the extra specifications are ignored. If the  number of columns specified
is less than the  <emphasis>ncols</emphasis> attribute, the final specification
is replicated  to cover the actual number of columns.</entry></row>

<title>DESCRIPTION</title>
<para>The <literal>frmtstyle</literal> element provides semantic, font and
formatting information for <literal>virpage</literal>, <literal>block</literal>
and <literal>p</literal> elements.</para>
<para>When a one of the elements listed in the FRMSTYLE Synopsis is encountered
in the document and that element has an <emphasis>ssi</emphasis> attribute,
the <literal>toss</literal> list of <literal>frmtstyle</literal> elements
is serached with an attempt made to match the <symbol role="Variable">class</symbol>
and <emphasis>ssi</emphasis> attributes of the element to the
<symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of
the <literal>frmtstyle</literal>. If the <literal>frmtstyle</literal> specifies
an <emphasis>rlevel</emphasis> attribute, the search is further refined by
matching the <literal>level</literal> of the element containing the element
to the <emphasis>rlevel</emphasis> of the <literal>frmtstyle</literal>. If
the element does not have a <symbol role="Variable">level</symbol> attribute,
the level of its containing element is used, and so on. A <literal>frmtstyle</literal> element with no <emphasis>ssi</emphasis> specified matches any <emphasis>ssi</emphasis> in a formattable element although an explicit <symbol role="Variable">class</symbol>/<emphasis>ssi</emphasis> pair is chosen in preference.</para>
<para>When a match is found, the font and style information contained in the <literal>frmtstyle</literal> is used in formatting the element.</para>
<para>The attributes of <literal>frmtstyle</literal> are:</para>

<title>DESCRIPTION</title>
<para>The <literal>grphstyle</literal> element provides semantic, font and
formatting information for <literal>refitem</literal> elements with a
<symbol role="Variable">class</symbol> attribute taken from the <emphasis>graphic</emphasis> class.</para>
<para>When a one of the above elements is encountered in the document and
that element has an <emphasis>ssi</emphasis> attribute, the <literal>toss</literal> list of <literal>grphstyle</literal> elements is searched with
an attempt made to match the <symbol role="Variable">class</symbol> and <emphasis>ssi</emphasis> attributes of the element to the <symbol role="Variable">class</symbol>
and <emphasis>ssi</emphasis> attributes of the <literal>grphstyle</literal>. If the <literal>grphstyle</literal> specifies an <emphasis>rlevel</emphasis> attribute, the search is further refined by matching the
<symbol role="Variable">level</symbol> of the element containing the element to the <emphasis>rlevel</emphasis> of the <literal>grphstyle</literal>. The <symbol role="Variable">level</symbol> of a <literal>refitem</literal> is taken from the <symbol role="Variable">level</symbol> of its enclosing block. If the enclosing block does not have
a <symbol role="Variable">level</symbol> attribute, the <symbol role="Variable">level</symbol> of its enclosing <literal>virpage</literal> is used. A <literal>grphstyle</literal> element with no <emphasis>ssi</emphasis> specified, matches
any <emphasis>ssi</emphasis> in a <literal>refitem</literal> element, although
an explicit <symbol role="Variable">class</symbol>/<emphasis>ssi</emphasis>
pair is chosen in preference.</para>
<para>When a match is found, the style information contained in the <literal>grphstyle</literal> is used in formatting the graphic.</para>
<para>The attributes of <literal>grphstyle</literal> are:</para>
