According to the HTML specs, <tag att> is equivalent to <tag att="att">. Also XHTML mandates lower-case tags (which incidentally, are easier to type). I guess you should go for ['img', { ismap => 'ismap' }] just to be on the safe side.

update: just FYI: XHTML doesn't allow attributes without values, so in XHTML you need to do att="att".
