Note that it may also be addressed by the exsl community-based XSLT
extensions in XSLT initiative [1] currently being thrashed out on

This features an exsl:return element which can return the same kind of
things that can be put into a variable - ie content by value, the
results of a select expression by reference. There's also a proposal for
an exsl:reference-of. (But returning results-of-a-selectexpression by
reference will in any case be way more powerful once we're defining the
functions that can go into these self-same select expressions...)
