   This example shows a request for an exclusive write lock on a
   collection and all its children.  In this request, the client has
   specified that it desires an infinite length lock, if available,
   otherwise a timeout of 4.1 billion seconds, if available. The request
   entity body contains the contact information for the principal taking
   out the lock, in this case a web page URL.

   The error is a 403 (Forbidden) response on the resource
   http://webdav.sb.aol.com/webdav/secret.  Because this resource could
   not be locked, none of the resources were locked.  Note also that the
   lockdiscovery property for the Request-URI has been included as
   required.  In this example the lockdiscovery property is empty which
   means that there are no outstanding locks on the resource.

   In this example, the nonce, response, and opaque fields have not been
   calculated in the Authorization request header.

8.11 UNLOCK Method

   The UNLOCK method removes the lock identified by the lock token in
   the Lock-Token request header from the Request-URI, and all other
   resources included in the lock.  If all resources which have been
   locked under the submitted lock token can not be unlocked then the
   UNLOCK request MUST fail.

   Any DAV compliant resource which supports the LOCK method MUST
   support the UNLOCK method.

8.11.1 Example - UNLOCK

   >>Request

   UNLOCK /workspace/webdav/info.doc HTTP/1.1
   Host: webdav.sb.aol.com
   Lock-Token: <opaquelocktoken:a515cfa4-5da4-22e1-f5b5-00a0451e6bf7>
   Authorization: Digest username="ejw",
      realm="ejw@webdav.sb.aol.com", nonce="...",
      uri="/workspace/webdav/proposal.doc",
      response="...", opaque="..."

   >>Response

   HTTP/1.1 204 No Content

   In this example, the lock identified by the lock token
   "opaquelocktoken:a515cfa4-5da4-22e1-f5b5-00a0451e6bf7" is
   successfully removed from the resource
   http://webdav.sb.aol.com/workspace/webdav/info.doc.  If this lock
   included more than just one resource, the lock is removed from all
   resources included in the lock.  The 204 (No Content) status code is
   used instead of 200 (OK) because there is no response entity body.

   In this example, the nonce, response, and opaque fields have not been
   calculated in the Authorization request header.

9  HTTP Headers for Distributed Authoring

9.1 DAV Header

   DAV = "DAV" ":" "1" ["," "2"] ["," 1#extend]

   This header indicates that the resource supports the DAV schema and
   protocol as specified. All DAV compliant resources MUST return the
   DAV header on all OPTIONS responses.

   The value is a list of all compliance classes that the resource
   supports.  Note that above a comma has already been added to the 2.
