RE: [Bug 3] Bindings draft should specify if all properties MUST have same value on all bindings

I think it would be good to include the following language in the bind

Note that, consistent with [RFC2518], the value of a dead property is
independent of the number of bindings to its host resource, and of the path
submitted to PROPFIND. Since live properties can be aribtrary computational
processes, they MAY vary depending on path or number of bindings, but SHOULD
NOT do this unless the definition of the live property explicitly includes
this dependency.

Here I avoided adding new requirements in areas already covered by 2518, but
did add requirements for the new situation raised by the BIND specification.
