Thanks, that's just the kind of trapdoor to escape from pattern to XSLT
that I would never have thought of.  I'll need a mild tweak to it to deal
with the fact that there might be a conflict between two or more
customization layers since each can define its own is-class-figure(), but
that's just a Simple Matter of Programming.

I'll suggest it to the toolkit team when it drops support for XSLT 1.0.
