Issue: RPC and Encoding fault combinations

 Hi all, 8-)
 (please remove xmlp comments from the receiver list when 
replying)

 In SOAP Encoding [1] it says that a SOAP receiver

>>SHOULD generate an "env:Sender" SOAP fault with a subcode 
of enc:MissingID if the message violates the constraints on id 
and ref attribute information items (see 3.1.5.3 Constraints on 
id and ref attribute information items).<<

 In SOAP RPC [2] it says that 

>>A fault with a Value of "env:Sender" for Code and a Value of 
"rpc:BadArguments" for Subcode MUST be generated when the
receiver cannot parse the arguments or when there is a mismatch
between what the receiver expects and what the sender has sent.<<

 It is unclear what should happen when both these conditions are
met - RPC server cannot parse arguments because of a missing ID.  
Technically, the RPC fault is a MUST and the Encoding fault is a
SHOULD, so the former takes precedence, but is this the
intention?

 I'd like a clarification on the relationship of these faults.
