Issue: Problem with ProcedureNotPresent fault subcode

Minor nit - in section 4.3 in part 2, it is stated that the
"rpc:ProcedureNotPresent" Subcode MUST be used in the following case:

	A fault with a Value of "env:Sender" for Code and a
	Value of "rpc:ProcedureNotPresent" for Subcode MUST
	be generated when the receiver does not support the
	procedure or method specified.

However, there is nothing in the message that indicates that a SOAP
message is following the RPC convention and nothing that prevents the
RPC convention from being used selectively in the SOAP receiver (if at
all). As a result it is not possible for the SOAP receiver to know
whether a message is following the RPC convention or not nor whether it
should respond using this fault or not. In other words, this requirement
is not enforceable.

I would therefore suggest that we change it to a "MAY" so that it says

	A fault with a Value of "env:Sender" for Code and a
	Value of "rpc:ProcedureNotPresent" for Subcode MAY
	be generated when the receiver does not support the
	procedure or method specified.
