Issue: Endpoint reference as a wsdl extension

The WSDL binding specification[1] says:

"When a wsa:EndpointReference element is present in a wsdl20:endpoint  
or a wsdl11:port element (see 4.1 Extending WSDL Endpoints with an  
EPR), the value of the [reference parameters] message addressing  
property for a message sent to an endpoint MUST include the contents  
of the wsa:ReferenceParameters element, if one exists within that EPR."

My take on this requirement is that this only applies if WS- 
Addressing is active for the message exchange but some readers have  
taken this to mean that the reference parameters have to be included  
regardless.

I suggest we add a clarifying note to the start of section 4 along  
the lines of: "Note: the WSDL extensions described in the following  
subsections are only active when WS-Addressing is engaged in a  
message exchange, if WS-Addressing is not engaged they are ignored".

Thanks,
Marc.
