The Hypertext Transfer Protocol (HTTP) Extensions for the Web
Distributed Authoring and Versioning (WebDAV) do not define the
behavior for the "POST" method when applied to collections, as the
base specification (HTTP) leaves implementers lots of freedom for the
semantics of "POST".

This has led to a situation where many WebDAV servers do not
implement POST for collections at all, although it is well suited to
be used for the purpose of adding new members to a collection, where
the server remains in control of the newly assigned URL.  In fact,
the Atom Publishing Protocol (AtomPub) uses POST exactly for that
purpose.  On the other hand, WebDAV-based protocols, such as the
Calendaring Extensions to WebDAV (CalDAV), frequently require clients
to pick a unique URL, although the server could easily perform that
task.

This specification defines a discovery mechanism through which
servers can advertise support for POST requests with the
aforementioned "add collection member" semantics.  [STANDARDS TRACK]
