No, it doesn't. In XSLT 1.0 (sans xx:node-set()) you are only allowed to do
two things with an RTF, namely to copy it using xsl:copy-of and to use it in
a context where a string would be accepted. That means that a node in an RTF
can never become the context node, which means that you can't select within
an RTF using the key() function.

Nice try.
