RE: [xsl] Calculations involving measurements with units

["Michael Kay" <mhk@xxxxxxxxx>]

XSLT 2.0 lets you write stylesheet functions that can be called from
within an XPath expression, which solves this problem.

In 1.0 you could try breaking the expression up by using variables, but
of course these can't take arguments in the way that a template or
function can.
