+1 to that.  Just to add a note, I do have some ideas about extending
our regex parser so that it could duplicate the XQuery syntax --- none
of the points we mention in 9.7.3.8 seem insurmountable.  I'm not
planning to work on that in the near future, mind you, but I definitely
think that we don't want to paint ourselves into a corner where we've
already implemented the XQuery regex functions with the wrong behavior.
