[OAI-implementers] resumptionToken and metadataPrefix

In both 1.x and 2.0, resumpToken is listed in all cases as an
-->exclusive<-- argument, meaning that: "the argument may be included
with request, but must be the only argument (in addition to the verb
argument)."  So, it is incorrect to require or even accept a
metadataPrefix with it.

Let me know if you have any further questions.
