Thanks Andrea, that actually does seem to work. So I could proceed with
that, but it sounds like you are both recommending better use of the
parameters to improve performance. I'm not sure I totally follow that yet,
but and doing some experimentation now.
By the way on my previous xml snippet - that must have been copied from an
older version... I have already discovered that the matchcase="true"
attribute messes things up. I have not been using that lately.
