Versioning is specified in the WebDAV deltav extension, which has been
submitted to the IESG in October.

And why is the fact that locking is optional a problem? If you hit a server
that doesn't support locking while youre application requires it -- just
don't talk to it. I agree that it would be a shame if major vendors come out
with "WebDAV" servers without locking support (is this the case? IIS and
Apache support it).

Actually, I'd say the fact that WebDAV uses well-defined HTTP method names
makes it *less* likely that security is compromised (as compared to XML-RPC
or SOAP).

I agree. RFC2518 badly needs a review, and I think this is the next work
item for the Working Group.

Doesn't come extensibility (the ability to marshall "anything") with the
price of being *harder* to control?

(I think we're getting out-of-topic...)
