rfc4709 (WebDAV Mount)

This RFC documents a mechanism that allows clients to find the WebDAV mount associated with a specific page. It's unclear to the writer what the value of this is - an alternate resource in the HTML page would also do.

As far as I can tell, there is only a single server side implementation and a single client side implementation of this RFC. I don't have access to the client implementation (Xythos Drive) and the server side implementation is in SabreDAV.

Experimental support for WebDAV Mount is available in the 'mount' branch, but won't be merged without a good use case.
