RE: losing element tags during copy-of

The value of current-grouping-key() is always an atomic value, never a node.
When you do group-by=".", the node is atomized to evaluate the grouping key
(which will be of type xs:untypedAtomic - for practical purposes, a string).
You can output the first item in the group using <xsl:copy-of select="."/>
which will give you the element structure. Other items might have been added
to the same group even though their internal markup is different, because
it's ignored in calculating the grouping key.
