The question is do we support unpaired response/request messages. A 1.2
version client may send a request for an operation which is unsupported
for a 1.2 server but unknown for a 1.1 server. So clients have to deal
with unpaired response/request messages anyway.
Another example could be that a searchRetrieveRequest with the
"scanOnFail" flag set responds with a scanResponse when a search fails.
The alternative would be to use extraResponseData for the results.

To reiterate what was discussed last time:
If you receive an unknown operation in SRW, you return a SOAP fault.
If you receive an unknown operation in SRU, you return an explain
response with a diagnostic, or if the operation parameter is omitted.
If you recieve an unsupported extension, then you must return the type
response that is paired with the request. You may return a
but there is no requirement to do so, as extensions can be silently
If you recieve an unsupported operation, you should return the right
of response with a diagnostic. Just a boilerplate "I don't do that"
answer will suffice.
