+1.

This was once proposed as MKRESOURCE (early drafts of the redirect 
spec), but later rejected.

I would argue in favor of keeping the top level argument, because it's 
consistent with all the later WebDAV specs.

Again, I would propose to leave things as defined for consistency with 
other methods.

DAV:resourcetype can not be a dead property. Ever.

I think the examples contain more.

That being said, I'd propose to leave out everything about RFC3253.
