Re: exsl:node-set and Saxon 6.5.5

I think I remember Michael commenting that the saxon6 implementation of
the node-set extension actually _changes_ the specifed RTF variable into
a node set, so if you access it later it is in fact allowed. probably
this isn't a feature that you should rely on though, especially if you
use it as exslt:node-set (which aims to be portable) rather than
saxon:node-set. All this is conformant(probably) as extension functions
in xslt1 may do more or less anything within reason.
