Re: Issue 125: Protocol precondition requires knowledge of policies

 The protocol clearly defines faults that are used if you have the wrong 
choice of RM enabled or not.
If the RMS tries to initiate a Sequence with an endpoint that doesn't 
support it there will be a fault (either CSRefused or a generic fault). 
If the RMS doesn't create a Sequence then we have the RMRequired fault.

It is possible to read this text in a good light. But I don't think its 
very clear. I'd be very happy to see some better words in there, but I 
would prefer no words to the ones there currently.
