Re: dimension arithmetic in xpath

> can anyone see a way I can get this to work?

Presumably them that know about these things could write an extension
function that got java to do the sums and return a length.

Or more portably you could use the string-replace named template posted
to this list a couple of times and replace 
'mm' by ' * 1 '
'pt' by ' * 2 '
etc where 1, 2 , are whatever the right conversion factors are to
convert everything to some common unit (eg pt).
then you can evaluate as an xpath number expression, and stick 'pt' on
the result.
