Re: [docbook] How to encode subfigures?

Thank you for all these answers, I did not expect so many of them!

Semantically, the solution of using informalfigure and caption does not seem appropriate: I would use a title for the figures outside the special case of subfigures; indeed, the subfigures have a title—which an informalfigure does not allow.

My main goal, for now, is more long-term storage than an immediate need, so I am taking the GitHub issue road, but I'm taking your suggestions for my immediate needs (without XSLT customisation for now, as I can live without xrefs towards subfigures).

@Dave Pawson: it's rather two pictures, but very closely related, with one common caption, and some details added for each of the two pictures (instead of two figures whose title is a mix between the common caption and the subfigure addition).

There are several ways to skin this cat. One is exactly what you have.
Depending on the [graphical?] content of the figures, you could have
Two other possibilities are:

<figure xml:id="somename">
<title>figure title</title>
<mediaobject xml:id="somename-a">
<imageobject>
<imagedata format="png" fileref="pic-a">
<info>
<title>caption for subfig a</title>
</info>
</imagedata>
</imageobject>
</mediaobject>
<mediaobject xml:id="somename-b">
<imageobject>
<imagedata format="png" fileref="pic-b"/>
<textobject>
<para>Caption for subfig b</para>
</textobject>
</mediaobject>
</figure>

We always write our own XSLT, so we have a handler to resolve the IDREFs
which point at these, and it's a house business rule to use the
convention of parent id with a hyphen and letter for naming multiple
mediaobject IDs.
