I think that will be what users most frequently want, and I don't think we want to wait for DASL to handle this important query. </eric> <eric> I also disagree with Tim's claim that this is the same as a DELETE happening while you weren't paying attention. Let's take the case where I know that I'm the only person operating in a particular section of the URL hierarchy (I have my own virtual single-user system). Clearly, I know that no delete has occurred, yet I'm seeing garbage in my directories because I have a bug in my currently selected RSR's. </eric> Ah, now you're adding constraints (single-user) :-) I agree that it is going to be bizzare for clients that expect all listed members of a collection to be GET-able. Others have suggested a separate return code to show the client's assumption was wrong--I think this goes part way to appeasing the client, but I suspect they will still be confused. It would be similarly bizzare for a collection to change it's apparent members based on how the RSR selects (or not) it's members revisions; so I'm prepared to live with the current situation. Even without a "bug" in the RSR, it is perfectly valid (and likely) to have resources that don't select a revision. Tim
