RE: Possible bug in SOAP 1.2 description of fault generation

Noah,

I can see how that can be confusing. I think your second rewording
captures the intent well:

* "Failure is indicated by the generation of a fault (see 5.4 SOAP
Fault) SOAP message processing MAY result in the generation a SOAP
fault; more than one SOAP fault MUST NOT be generated when processing a
SOAP message."

Thanks for taking time to iron this out although I am not sure what the
best process is to capture this as an erratum.
