Let's call that profile "filestore".

This profile would be a true subset of WebDAV. A server such as Slide 
(to take a real-world example) might want to advertise "filestore" on 
some resources (such as in a FS backend), but not others (such as a 
Tamino XML database).

A client that would absolutely need the features defined as part of the 
"filestore" would simply refuse to interop with some of the resources on 
the server.

IMHO that would still be far better than to forbid servers to implement 
useful WebDAV stuff on resources like these (because that's what a MUST 
or even a SHOULD requirement would essentially mean).

We also should keep in mind that we're in HTTP's area here, because 
we're talking about PUT. We simply can't overrule HTTP here. We *can* 
define a way for servers to advertise that their PUT support fulfills 
certain requirement, so that clients can find out.

Best regards, Julian
