Hi all,
I'm pulling my hair - thought this was easy, but turns out to be more
difficult. The \externalfigure command can take a width and/or a height
parameter, and context will be happy to take either one into account. I'm
trying to translate that into xml syntax. Here's a minimal example

Ah, expdoifelse is for expanded doifelse, right? Any examples for such a lua
helper? Sounds good, but I still haven't been able to understand how to mix
xml and lua code.
