The example seems like an artifact of an earlier design where the
content of a Transfrom was normally a single opaque possibly encoded
blob that only the Transform need understand.  But after that we moved
towards explicit parameters to Transforms being Parameter elements and
then decided that they should always be algorithm specific named

So it should really be

    <Transform Algorithm="&XPath;" xmlns:xp="&XPath;">
