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?
