Re: Filtering out duplicates in current-group()

because you can only apply templates to nodes (elements attributes etc)
but teh current-grouping-key  is the string value that's shared by all
the nodes in the current group, it's not itself a node.
you can value-of it to get its value, but you can't apply templates to
it.
