Test 1205 and the SOAP processing model

I have a question about test 1205 and the soap processing model. In the 
soap processing model we must check that we understand headers before we 
process any of them 
(http://www.w3.org/TR/2003/REC-soap12-part1-20030624/#procsoapmsgs). 
However, if I am using WS-Addressing to resolve my service and determine 
what headers it understands, how can I possibly know that I understand 
any headers at all?

Alternatively I can read rule #1 as such that I can inspect the 
information and then use it (i.e. wsa:To) to find out what headers are 
understood. But if I can do this (which qualifies to me as 
"processing"), why wouldn't I also act on the FaultTo in test 1205 and 
not the send a fault out?

Cheers,
- Dan
