Alan's responses make me realize that the true force of the Con arguments was left implicit in the arguments as I summarized them, or perhaps the issue should be once again reframed. Let me try to make that explicit. DASL servers themselves must independently validate any query. They cannot rely on clients submitting only valid queries. (While not everyone agrees with every argument advanced for this point, I think everyone agrees with at least one of them.) If this is true, then it calls into question the value of client side error checking. Alan argues that such checking is very desirable in UIs. (P2 makes this point). Someone else might argue that such checking is redundant, since the server will repeat it regardless, and that redundancy, per se, is a bad thing, and since the only proposed means to support such client side checking is so unappealing. So perhaps the argument is really over whether there ought to be a requirement that DASL enable agents (client side apps) to assist users to construct valid queries, e.g. by preventing them from constructing invalid ones. I hope someone besides Alan (whose position is clear already) or I (who is simply trying to keep this discussion clear) will speak up.
