Felix, just to explain my reluctance for regex comes from the simple
fact that no regex is better then wrong one. Now with grammar for our
regex subset this is no more issue - almost. For example in past there
were some requests to allow only BMP characters in regex not full
Unicode. It would be very hard to express this in regex for engine that
has full Unicode coverage (which is default for xs:pattern/rng:pattern).
