RE: [xsl] last() and distinct-values 2.0

["Michael Kay" <mike@xxxxxxxxxxxx>]

You appear to have found a Saxon bug. I'll look into it.

Note that there is no need to use a namespace with the distinct-values()
function in XSLT, any more than you need a namespace with position() and
last() - and it's better not to use the namespace, because it is still
changing in each draft.
