Hmm, almost... Gives the dreaded "Missing number, treated as zero" error. But your
"fit" gave me an idea: this works:
[height=\xmlattdef{#1}{height}{fit}]
but only if I have a real dimension as in height="5cm". What if I want to define
something like height="0.4" and want this to be the equivalent of height=0.4\textheight ?
This of course doesn't work:
[height=\xmlattdef{#1}{height}{fit}\textheight]
since it will expand to "fit\textheight" as a default option. Any suggestions?
something (slow):
\expdoifelse
{\xmlattdef{#1}{height}{fit}
{fit}
{\xmlatt{#1}{height}\textheight}
(of you define a lua helper)
