async capability issues.

[Gary P Cole <Gary.P.Cole@Sun.COM>]

I raised three issues while writing the Protocol/Async Capability section.
To summarize, these are:

1) Remove (optional) requestID from SpmlRequestType
     and add (required) requestID to CancelRequestType
     and add (required) requestID to StatusRequestType

2) Don't need CancelResultsType; ResultCode and ErrorCode should suffice.

3)  Replace "statusReturns" with optional boolean attribute "returnOutput".

Does anyone object (or wish to suggest a refinement) to these proposals?
