RE: HTTP Method selection

This is now issue CR123. A proposal is to add a sentence along the lines of 

"Conformance to this (HTTP) binding requires conformance to the wsdlx:safety
extension [ref]."

Or if you don't like "conformance",

"Implementations supporting this binding must also support for the
wsdlx:safety extension [ref]."
