Thanks for the clarification, Ted.

Personally, I think this would be a step into the wrong direction. There 
are scenarios out there today that work perfectly fine without locking, 
and there are servers that do not support locking at all, or do not 
support it for specific resources.

Making locking mandatory in future specs will not affect these servers 
(nor the clients that work with them). In the best (or worst?) case they 
will be upgraded to include other -bis features, claim compliance but 
still will not support locking.

On the other hand, clarifying that locking *is* optional, and publishing 
a much simpler base WebDAV spec (sans locking) my actually convince 
potential server implementers to implement those parts of RFC2518 
(namespace operations + metadata) and therefore increase WebDAV's
