I find myself struggling with a construct I often need: conditionally,

do something radically different depending on input.
For example:
<xsl:variable name="el" select="elements" />
<xsl:if test="count($el)">
But you don't need a variable above, test="location-path" will return false
if the return is an empty node-set.
Yes, I did it for keeping the (large) pattern in one place instead of two, and
for optimization, to have it evaluated only once. But that's perhaps
unnecessary?
Cheers,
