/**
* Maps between WebDAV lock tokens and JCR lock tokens.
*
* The following notations are used:
*
*
* opaquelocktoken:SESSIONSCOPED:NODEIDENTIFIER
* opaquelocktoken:OPENSCOPED:JCRLOCKTOKEN
*
*
* The first format is used if the JCR lock does not reveal a lock token, such
* as when it is a session-scoped lock (where SESSIONSCOPED is a constant UUID
* defined below, and NODEIDENTIFIER is the suitably escaped JCR Node
* identifier).
*
* The second format is used for open-scoped locks (where OPENSCOPED is another
* constant UUID defined below, and JCRLOCKTOKEN is the suitably escaped JCR
* lock token).
