<textual-form>

Textual Form

A container element that holds text (mixed content), this element is used in places where alternatives can be presented, to provide a textual alternative. For example, inside the <alternatives> wrapper element, a <textual-form> can provide an alternative version of an equation, graphic, or table. This alternative textual version may be a direct textual representation of an object (such as Unicode for a special character or the full text of an equation in ASCII characters), or a simplified textual version of the object (for display by devices not able to cope with the object), or a text-dump of the contents of a binary object (for example, the full text-dump of the cells of a table to accompany a graphical version of the table).

Model Description

Any combination of:

This element may be contained in:

<alternatives>, <chem-struct-wrap>

Example 1

A formula/equation as a graphic, a MathML-tagged equation, and a textual form:

...
<disp-formula>
<alternatives>
<textual-form>(a + 3)<sup>2</sup> - (10 - b) = 24</textual-form>
<graphic xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="fors2682.f3"  >
<object-id>463492</object-id>
</graphic>
<mml:math>
<mml:mrow>
<mml:msup>
<mml:mfenced>
<mml:mrow>
<mml:mi>a</mml:mi>
<mml:mo>&plus;</mml:mo>
<mml:mn>3</mml:mn>
</mml:mrow>
</mml:mfenced>
<mml:mn>2</mml:mn>
</mml:msup>
<mml:mo>&minus;</mml:mo>
<mml:mfenced>
<mml:mrow>
<mml:mi>10</mml:mi>
<mml:mo>&minus;</mml:mo>
<mml:mn>b</mml:mn>
</mml:mrow>
</mml:mfenced>
<mml:mo>&equals;</mml:mo>
<mml:mn>24</mml:mn>
</mml:mrow>
</mml:math>
</alternatives>
</disp-formula>
...

Example 2

An example of a triple bond glyph. To a chemist, a triple bond is not the same as Unicode x2261, but using alternatives, as shown below, is sometimes the easiest way to display the character visually and still stay within Unicode.

Example 3

A text-dump of a table, for use in searching and indexing:

...
<table-wrap id="tbl-3">
<label>3</label>
<caption>
<title>Categories of Color Immediacy</title>
</caption>
<alternatives>
<graphic id="tbl3-jpg"
xlink:href="immediacy-tab3.jpg" />
<textual-form specific-use="search/index">
Description of Color Category
Number of Immediacy Events

1. Drew parallels between green and blue relationships
21 events

2. Encouraged expression of yellow feelings
12 events

3. Admitted red termination
8 events
...

Note. These results are based on 44 immediacy events.
Categories were not mutually exclusive, and several types of
immediacy may occur in each event. Each category was
recorded only once per event.
</textual-form>
</alternatives>
</table-wrap>
...

Example 4

An alternate textual description of a graphical object, that may include face markup. In this usage, the <textual-form> element is intended for display in devices that do not possess the full power of a browser or do not have the ability to display graphics. (The element <alt-text> performs a similar function but has an even simpler face-markup-free model for accessibility uses.)
