OK,

given the lock tokens L2 for C2 and L3 for C3, I'd say the REBIND 
request would be:


REBIND /CollW HTTP/1.1
If: <http://example.com/CollW/CollY/CollZ> (<L3>) 
<http://example.com/CollW/CollX> (<L2>)
Overwrite: T

<rebind xmlns="DAV:">
   <segment>CollX</segment>
   <href>/CollW/CollY/CollZ</href>
</rebind>

Reason: we need to supply both lock tokens as we're removing a binding 
to C3 that is protected by the lock L3, and we're removing the target 
binding /CollW/CollY which is protected by the lock L2.


Best regards, Julian
