Well, that the "innocent looking equality comparison" has the meaning of
"exists in" in XSLT 2 and is IMO one of the first things you have to learn
when switching from XSLT 1.0. Whoever takes 2.0 serious b compared to just
changing the version attribute of the xsl:stylesheet b will know about

Also, I believe that any decent XSL processor will create a hash on $names and
therefore deliver about the same performance compared to xsl:key.
