RE: performance and the xsl:for-each-group instruction

I would expect the performance to be fairly similar. Muenchian grouping is
pretty efficient, it's hard to improve very much on it. The big advantage of
xsl:for-each-group (at least with the group-by option) is usability, not
performance.

# Does the xsl:for-each-group instruction have a performance 
# benefit over using the Muench method, or is it just syntactic

# Muench method in Saxon 7.8 and I don't see any performance 
# gain.  It would make sense (at least to me) that 
# xsl:for-each-group could operate much more efficiently than 
# the Muench method since it knows what you want to do is group.
