Anyone got suggestions as to how one picks a random node out of a
node sequence?

exslt has a random function or depending on how random and/or repeatable
you need the result you can in xslt 2 use the time of day to give you
some number of seconds.

I assume you are using xslt 2 as your code snippet uses eq although
originally I'd assumed you needed an xslt 1 answer as xpath2 doesn't
have node sets (that was the datatatype in xpath 1)
