[issue 6432] - a modest proposal

Would it be too bold to suggest folks consider to move NotifyTo to be  
a child of Subscribe?
that way, then Delivery could be used (as an xs:Any) extension point,  
used by other specifications to mean anything they want at at cost of  
merely setting a SOAP mU header on delivery to get the fault  
behavior.  Of course, the fault would change from modeNotRecognized to  
SOAP mU Fault, but the other stuff would still work.
Is that half-way-ish approach that folks could consider?
