-For a list of possible values, see `vc-state'."

-  ;; up-to-date - use lockdiscovery

-See `vc-checkout-model' for a list of possible values."
-  ;; The only thing we can support with webdav is 'locking

-  "Return the current workfile version of URL."
-  "Unknown")

-(defun vc-dav-register (url &optional rev comment)

-If REV is non-nil, that should become the new revision number.
-COMMENT is used as a check-in comment."

-(defun vc-dav-checkout (url &optional editable rev destfile)
-  "Check out revision REV of URL into the working area.
-
-If EDITABLE is non-nil URL should be writable by the user and if
-locking is used for URL, a lock should also be set.
-
-If REV is non-nil, that is the revision to check out.  If REV is the
-empty string, that means to check ou tht ehead of the trunk.
-
-If optional arg DESTFILE is given, it is an alternate filename to
-write the contents to.

-  ;; This should LOCK the resource.

-(defun vc-dav-revert (url &optional contents-done)
-  "Revert URL back to the current workfile version.
-
-If optional arg CONTENTS-DONE is non-nil, then the contents of FILE
-have already been reverted from a version backup, and this function
-only needs to update the status of URL within the backend.

-If REV1 and REV2 are non-nil report differences from REV1 to REV2.
-If REV1 is nil, use the current workfile version as the older version.
-If REV2 is nil, use the current workfile contents as the nwer version.
-
-It should return a status of either 0 (no differences found), or
-1 (either non-empty diff or the diff is run asynchronously).

-  "Estimate the version control state of URL at visiting time."

-;;; Unimplemented functions
-;;
-;; vc-dav-latest-on-branch-p(URL)
-;;    Return non-nil if the current workfile version of FILE is the
-;;    latest on its branch.  There are no branches in webdav yet.
-;;
-;; vc-dav-mode-line-string(url)
-;;    Return a dav-specific mode line string for URL. Are there any
-;;    specific states that we want exposed?
-;;
-;; vc-dav-dired-state-info(url)
-;;    Translate the `vc-state' property of URL into a string that can
-;;    be used in a vc-dired buffer.  Are there any extra states that
-;;    we want exposed?
-;;
-;; vc-dav-receive-file(url rev)
-;;    Let this backend `receive' a file that is already registered
-;;    under another backend.  The default just calls `register', which
-;;    should be sufficient for WebDAV.
-;;
-;; vc-dav-unregister(url)
-;;    Unregister URL.  Not possible with WebDAV, other than by
-;;    deleting the resource.
