Ah, I guess my intent was not clear.

The only constraint on the SOAPAction value is only when you are using 
the OperationName feature AND choose to engage both the OperationName 
feature and the SOAP Action feature together.

This feature's intent is not to require  SOAP Action values and what 
they should be.  This feature's  goal is to enable by the use of a 
property to convey the receiver the name of the operation  and it 
describes a variety of ways to implement this using different bindings. 
This is why I described  a SOAP module to do this in a completely 
transport independent way. SOAP specification does not state what the 
value should be, our intent was to illustrate the only way you get the 
value to be constrained this way is when you use the OperationName 
feature, because the intent is to convey the name of the operation, 
nothing else.

Other possible values for the SOAP Action is not part of this feature, 
another feature may define what they could be in some other context.
