I don't think RFC2518 defines any of these. This is why we were trying 
to find out what servers actually *do* implement, so that it can be 
clarified in RFC2518bis. IMHO, nobody seems to be doing this in practice 
(otherwise the bug in mod_dav would have surfaced earlier); thus 
RFC2518bis probably should say that you can't do a LOCK refresh that way.

Yep.

Thanks, Joe. Your work on Neon and Litmus is a really a big contribution 
to WebDAV.
