Hi Chris, Johannes Koch wrote: <quote> The HTML 4 DTDs forbid the nesting of form through exclusion: (...)

So this technique will, in effect, forbid nested forms. </quote> To my understanding, the techniques don't forbid anything, because they are non-normative documents. If you do nest forms, the conclusion should be that you are not using this technique, rather than saying that the technique forbids nested forms. I would formulate an argument against nested forms in a different way: since the HTML specification forbids nested forms (regardless whether this is in an SGML DTD - for HTML 4.01 - or in prose - for XHTML 1.x), nested forms can be seen as ambiguous to user agents, and therefore violate SC 4.1.1. I think the ambiguity resides in the relation between, for example, the submit buttons, the input fields and the action URL's: which belong with which? What gets submitted where when you activate 'submit'?
