The xsl:key match was turned into a path by prepending //, but for a union
match like "Level1 | Level2" the // applied only to the first branch
(//Level1 | Level2), so the second branch matched relative to the root and
found nothing, dropping those nodes from the key. Distribute // over each
top-level union branch (// inside a predicate or function call is left alone).
Closes Apache Xalan conformance cases idkey45, idkey46, idkey47, idkey48.
