 For simplicity sake, lets say that spec. should mandate atmost one
 PollRequest. This won't be a limitation as one can have one or more
 RefToMessageIds elements in it, be it for the same group or different.

 Advantage of having atmost one PollRequest is that Fault processing
 will be simple.

 Yes, RefToMessageIds can appear more than once.

 Here is what I had in my proposal for Rel 94:

 1.InvalidGroupId:  Even if one of the GroupIds are wrong or invalid, this
fault will be sent.
  2.InvalidSequenceNumber: Even if one of the SequenceNumbers is wrong or
     this fault will be generated and sent.

 Essentially, all or none approach wrt to Faults. We should be able to share
the above
 Status values with Fault  Codes. Note both  are QNAME types and hence

 So essentially your example will result in a Fault.

 Schema is correct in this case and Iwasa fixed this in the latest version/
 It is indeed an empty element.
