/**
* CalDAV Server - handle DELTICKET method in line with defunct proposed RFC
* from: http://tools.ietf.org/html/draft-ito-dav-ticket-00
*
* Why are we using a defunct RFC? Well, we want to support some kind of system
* for providing a URI to people to give out for granting privileged access
* without requiring logins. Using a defunct proposed spec seems better than
* inventing our own. As well as Xythos, Cosmo follows this specification,
* with some documented variations, which we will also follow. In particular
* we use the xmlns="http://www.xythos.com/namespaces/StorageServer" rather
* than the DAV: namespace.
