If $bad_emails_contains is a set of elements, then this won't work. The
contains() function expects a string. I think you might be trying to test
whether a node-set contains a given node (*please* don't try to guess what a
function does from its name alone!), in which case the XSLT 1.0 solution is

count($nodeset | $node) = count($nodeset)

The 2.0 solution is

exists($nodeset[. is $node])
