The other point we seem to disagree upon is that BIND should only be 
applicable to a certain class of servers that indeed can maintain the 
live properties the way many wish. I absolutely agree in that it's a 
good thing if a server behaves that way, but I also think that BIND 
shouldn't mandate that. We conceivably could do two things:

- in RFC2518bis, clarify the issues that arise because of the 
interaction between DAV:get* properties inherited from HTTP and the 
WebDAV namespace operations (for instance, state that a server must do 
post-namespace-op-cleanup of for instance DAV:getlastmodified; and also 
suggest that having strong entity tags that are unique across the 
server's whole namespace will make that unnecessary for DAV:getetag)

- define a specific profile (putting additional constraints on the 
behaviour of some of these live properties), and make that 
client-detectable (for instance through a specific DAV: header option).

Best regards, Julian
