34  * DELETE Method. The delete method can be sent to either a collection or
35  * non-collection resource. If a delete is sent to a collection, then all
36  * members of that collection are deleted.
37  *
38  * <p> Deletes can fail because of permission problems or if a resource is
39  * currently locked.
40  *
41  * <p> A typical request/response pair might look like this:
42  *
43  * <h3>Request</h3>
44  * <pre>
45  * DELETE /container/ HTTP/1.1
46  * Host: www.foo.bar
47  * </pre>
48  *
49  * <h3>Response</h3>
50  * <pre>
51  * HTTP/1.1 207 Multi-Status
52  * Content-Type: text/xml; charset="utf-8"
53  * Content-Length: xxxx
54  * &lt;?xml version="1.0" encoding="utf-8" ?&gt;
55  * &lt;d:multistatus xmlns:d="DAV:"&gt;
56  * &lt;d:response&gt;
57  * &lt;d:href&gt;http://www.foo.bar/container/resource3&lt;/d:href&gt;
58  * &lt;d:status&gt;HTTP/1.1 423 Locked&lt;/d:status&gt;
59  * &lt;/d:response&gt;
60  * &lt;/d:multistatus&gt;
61  * </pre>
62  *
63  * <p> In this example, the delete failed because one of the members was
64  * locked.
