Actually, this won't quite work as is, because toplevel elements in the
stylesheet have to be in some namespace.  You can use a dummy namespace you
make up just for this, but you can avoid having to do so by keeping the
original xsl:variable element and getting at the month names using good old
document(""), like this:

<xsl:variable name='month-lookup'
select='document("")/xsl:stylesheet/xsl:variable[@name="monthnames"]/month'/

(Of course, if you have no other xsl:variable elements you can omit the
predicate in the square brackets).
