Re: [xsl] Tricky inclusion match

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

groupa_count and groupb_count are really the collection of results
from the match on "record".  So the result for group a might be:

<groupa_count>
  <value>1</value>
  <value>2</value>
  <value>1</value>
</groupa_count>

The sum of group a would then be:  4
