I doubt that unrestricted backpointers to collection parents will be implementable on general web servers, but I have no objection to defining an optional backpointer property provided that it is also mentioned that such a property is not a very good way to implement scalable systems. I would expect any system that implemented such a thing would restrict the backpointers to references within the same object repository (whatever serves as the server backend). The same functionality can be accomplished via a DASL query, regardless of how the server backend works, which has the advantage of specifying the scope of the query. So, I don't think directly specifying a property to hold that information should imply that the property is maintained live. OTOH, I'm not sure how the response to such a DASL query would look like (i.e., if it would need DAV:references itself). ....Roy
