  Just as Michael's shown you.  See the resolve-QName definition there:

    http://www.w3.org/TR/xpath-functions/#func-resolve-QName

  That means that having elements 'elem' with an attribute 'a' which is
a lexical QName, you can select the elements where the attribute is
equal to a given QName (regarding the namespace bindings in scope on
its parent element) by:

    elem[resolve-QName(@a, .) eq xs:QName('ns:name')]
