new bug issue - can <catch faultName="qname"> catch a fault witha data body?

Bug Situation: 

According to our current fault matching rules IF a fault has a body
THEN it can only be three ways - by a catch that specifies the name and
body, by a catch that just specifies the body or by catch all. But
notice what can't catch it, a catch that just catches on the name.

That means, if someone needs to add a data body to the fault later (to
add optional interesting data) then all existing catches will be broken.

Potential Solution: 

It would be better to allow <catch faultName="qname"> to catch
with fault data body as well.
