RE: Issue 169: Propose http method in the operation interface to simplify http binding.

Does the latter principle apply outside of WSDL, that is to suggest that third parties should not extend wsdl:interface/* unless it maps to (nearly) all bindings?  

Doesn't that latter principle also say that "safe" should be moved into the binding?  For example, SMTP doesn't have a "safe" operation as defined by RFC 2616.  It's got "MAIL", "RCPT", "DATA", etc.  

Also, the motivation for "safe" is primarily HTTP specific but potentially useful for other protocols.  "safe" was added explicitly to give greater support to HTTP by allowing applications to indicate when bound to HTTP, a GET operation may be used.  Which is the same motivation for webMethod at the interface operation level, allowing applications to indicate when bound to HTTP, a particular opertion may be used.  Not much difference in my mind.

Cheers,
dave
