/**
* (from the spec) 7.4 Write Locks and Null Resources
*
* <p>It is possible to assert a write lock on a null resource in order to lock the name.
*
* <p>A write locked null resource, referred to as a lock-null resource, MUST respond with a 404
* (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
* collection. Additionally the lock-null resource MUST have defined on it all mandatory DAV
* 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.
