Issue 299: RPC return value accessor too complex

While I think that language in clause 2 of 4.2.2[1] could be clearer (
and am happy to make it so ), I think the current design works and is
consistent with the SOAP Data Model. So I propose we close this issue[2]
with no action beyond an instruction to the editors to tidy up the
language.
