Sorry if my bug description isn't clear. I understand what the difference is between an attribute being absent vs. being present but empty. What I'm asking to have clarified is whether <input type=button value=''> should be fine in this particular case or not. The change that was made for bug 10710 was for the spec to state that "A label for the button must be provided". So I guess the question I'm asking is, do we want the empty string count as a label in this case, or not (should a conformance checker emit an error message if it's empty)? 44115 4 ian 2011-01-11 06:26:33 +0000 Good question. I guess we should allow value="" on the basis that sometimes we will fill in the label later, for the same reason we allow empty paragraphs? 44322 5 hsivonen 2011-01-13 14:09:10 +0000 (In reply to comment #4) > Good question.
