I agree, and I think that is why people were happy enough to say that the response includes methods that are valid for different states of the same resource. > I mean, if I have a checked-out resource, and I don't > have an exclusive write-lock on the resource, then > requests to the server such as "If I try and commit, > will I be able to?" can only be usefully answered by > the server with: "I don't know, unless you try." Yes, and there are other examples. You could have changed the state of the resource (or DELETEd it for that matter) between me asking for the allowed methods and then actually issuing it. > Is there a more subtle issue I'm missing? Don't think so, other than to say the principal use of the supported-*-sets is to allow for resource 'classification' which is typically required for high-level UIs to choose icons, grey-out or enable menu options, and so on.
