Does the xsl:for-each-group instruction have a performance benefit over using the Muench method, or is it just syntactic candy?  I've been testing xsl:for-each-group against the 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.
