Here's something I feel I should know the answer to but don't. When you validate a URI, does it also check any javascript forms that are triggered from that page? I'm thinking not, because the forms don't appear in a view source (except as CDATA) and there's nothing different in the URI. But if it doesn't, how do you validate these types of javascript forms? Is Firebug's Validate Local HTML the best way or is there something more definitive?
