   * (Not Found) or 405 (Method Not Allowed) to any HTTP/1.1 or DAV methods except for PUT, MKCOL,
   * OPTIONS, PROPFIND, LOCK, and UNLOCK. A lock-null resource MUST appear as a member of its parent

   * properties. Most of these properties, such as all the get* properties, will have no value as a
   * lock-null resource does not support the GET method. Lock-Null resources MUST have defined
   * values for lockdiscovery and supportedlock properties.
   *
   * <p>Until a method such as PUT or MKCOL is successfully executed on the lock-null resource the
   * resource MUST stay in the lock-null state. However, once a PUT or MKCOL is successfully
   * executed on a lock-null resource the resource ceases to be in the lock-null state.
   *
   * <p>If the resource is unlocked, for any reason, without a PUT, MKCOL, or similar method having
   * been successfully executed upon it then the resource MUST return to the null state.
