Peter, 

I still maintain that you would be better off ordering your groups using the
values of the $sortcol rather than using the Muenchian method and a cunning
(but alas ineffective) sort. Once you've got the a series of current
@dataids in the right order you can use key to get all the relevant nodes.
If as you explain, the columns are quite complicated things it will still be
easier doing it this way.

so <xsl:key name="dataset" match="dataset" use=" 'all' "/>
and key("dataset", " 'all' ") 
doesn't work?
