I took another look at Charles solution and found the
explanation for the word 'union' (it's a key):
  <xsl:key name="union" match="group/table/col"
use="@month" />

So the 'select' statement now makes sense. Sorry for
posting unnecessarily.

I am now posed with another challenge. How do I use an
external lookup table to define the column headings?
E.g. Jan, Feb, Mar,...,Dec. Any pointers would be
appreciated.
