except I can't.
Error at xsl:for-each-group on line 54 of file:/C:/sgml/files/mu2.xsl:
  A sequence of more than one item is not allowed here
I.e. I've got multiple instances of the right loc element... i.e. a group.
I guess its the concat that's failing rather than the group-by?

I'm beginning to think that Jeni's version would be a good addition
to xslt 2.

what do you mean by 'hierarchical' numbering please Mike? The number would
only
relate to the last group? e.g. if it was (imagining)1.2.6.4 I'd only get the
4 when
asking for position() ? Is that it?
