Re: Issue: Problem with ProcedureNotPresent fault subcode

 Noah,
 thanks for this info. I think that in this case we must decide 
how we understand it in SOAP 1.2:
 a) first you understand the first QName in the Body, then you 
know it's RPC and the ProcedureNotPresent fault has no meaning 
then (and also it seems that RPC cannot forbid multiple 
invocations in one Body then),
 b) or RPC is application of SOAP governing the whole Body, in 
which case ProcedureNotPresent has sense.
 We are currently saying we don't mandate any kind of semantics 
in Body (except for the Fault), which would indicate that we'd 
better stick with (b) as then RPC gets to say what Body is (as 
opposed to some higher level of contract which uses RPC for 
particular QNames).
 Best regards,
