the input type=image element's ismap attribute is missing, did this get missed, deprecated, obsoleted or overlooked? I searched these pages and bugzilla http://www.w3.org/html/wg/drafts/html/master/forms.html#the-input-element http://www.w3.org/TR/html5/forms.html#the-input-element It makes a brief mention here: http://www.w3.org/TR/html401/struct/objects.html#adef-ismap
Judging from that usemap is deprecated on the input as well, I would say it is deprecated and missing a mention is all.
