Search engines have no business submitting forms, so that's a pretty red herring. And screen readers can handle JavaScript and modified DOMs just fine. The problem isn't actual accessibility, but accessibility guidelines based on outdated technology. Laws relating to the computer world will ever be thus -- by the time legislation can be draughted and passed, a couple of Moore's Law cycles have gone by. But if you're working under a guideline, it really doesn't matter whether or not the guidelines are technically current, they're still The Law.
You can get a perfectly good old-school server-side validation going without _doClick(), but it involves printing the form back to the browser from your WQS (after setting SaveOptions to "0"). That can be made a whole lot less painful if you keep your major passthru HTML stuff in profile docs and use computed text (or CFD fields) in passthru on the form -- you can use the same profiles to generate the printback form. No sequence number is necessary, since your action will either be CreateDocument or SaveDocument.
