Mark up Presentation content in Presentation XML

[opoudjis]

Presentation XML introduces presentation-specific content—such as autonumbers and delimiters—which we may (may) in future want to identify and render differentially in different renderers. To that end, we will tag the content we introduce; renderers will just pass through the contents of those tags.

This resolves the (phantom) issue introduced in metanorma/metanorma-ogc#472

So whereas right now we convert Semantic XML

<clause id="A"><title>Scope</title>....

to

<clause id="A"><title>1.<tab/>Scope</title>....

We will in future mark this up as

<clause id="A"><title><autonumber>1</autonumber><autonumber-delimiter>.<tab/></autonumber-delimiter>Scope</title>....

Where renderers will almost always (currently: always) render autonumber and autonumber-delimiter as the contents thereof.

From Ronald:

<termnote id="_" keep-with-next="true" keep-lines-together="true">
                <name>Note 1 to entry:</name>
                 <p id="_">The starch of waxy rice consists almost entirely of amylopectin. The kernels have a tendency to stick together after cooking.</p>
               </termnote>

I find it a bit strange that "name" is mixed with "p" and assumed to flow as spans. The element name "name" probably works better with something like "content" or "description".

Also, by moving the colon inside "name", it is now conflating the "name of the note" with a delimiter. Cross references or an index that link to this note will not use the delimiter.

The name is an inherited semantic tag, for the caption of the block. There will be no refactoring of Semantic XML in addition to the refactoring of the Presentation XML

The way to address the concern about separating captions, numbers, and delimiters, is going to be by introducing a separate fmt-name caption element, giving the presentation form of the caption, with its contents semantically annotated:

Semantic XML:

<note id="_" keep-with-next="true" keep-lines-together="true">
     <name>Concerning waxy rice</name>
     <p id="_">The starch of waxy rice consists almost entirely of amylopectin. The kernels have a tendency to stick together after cooking.</p>
 </note>

Presentation XML:

<note id="_" keep-with-next="true" keep-lines-together="true">
     <autonum>3.1</autonum>
     <name>Concerning waxy rice</name>
     <fmt-name><span class="autonum">3.1</span><span class="autonum-delim">:</span> 
         <span class="name">Concerning waxy rice</span></fmt-name>
     <p id="_">The starch of waxy rice consists almost entirely of amylopectin. The kernels have a tendency to stick together after cooking.</p>
 </note>
