Hi Hugo,

Ok, good.

I am too.  It's a lot more "in your face" than I was expecting would
ever be proposed, but that's fine by me.  In a similar earlier proposal
of mine, I didn't even attempt[1] to touch the interface, because I knew
it would be immediately shot down due to the perceived value of (ahem)
"protocol independence".

I would also suggest that some prose be added to make the implication of
using this attribute clear to developers.  Specifically, they need to be
aware that when it's used, an operation name becomes purely
documentation.  So for this example ...

  <wsdl:operation name="putStockQuote" wsdl:webMethod="PUT">

the WSDL spec needs to be clear that the semantics of the contract are
PUT, and not putStockQuote.  i.e. a successful response from a document
being submitted to that endpoint, only means that PUT was invoked, not
that putStockQuote was invoked.  Perhaps making name optional would be
useful, and discouraging its use when "webMethod" is used??  Dunno.

BTW, I think we can do better than "webMethod" as the name, since it's
not just for "Web" ("uniform"?) methods, it's for any method of an
underlying application protocol, e.g. FTP STOR, SMTP DATA, etc..  What
about "protocolMethod" (ick)?  Hmm, can't think of a good one.

Sounds good.  I'm sure Dave intended that.
