At the moment, the optional pseudo-class doesn't seem to follow any of this rule. Indeed, "button" isn't an element the user can fill so, show it as "optional" sounds weird. The same way, "input elements that are not required" should be changed to "input elements for which the required attribute applies but without the required attribute specified" so button, hidden, image, reset and submit input types don't match the rule. The difference between behavior 1 and behavior 2 is the the select element and I'm wondering why it can't be required. It sounds reasonable to let it matches :optional but it should be great to have it matches :required too. See bug 9625. To summarize, button elements should not match the :optional pseudo-class nor input elements for which the required attribute doesn't apply. 39322 1 ian 2010-09-25 00:35:28 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
