Wouldn't that be an argument in _favour_ of the hyphen? We want to have 
consistent naming, otherwise we'll have authors wondering "so wait, is 
this the attribute with the hyphen, or with the underscore?". In 
particular, HTML already has four different ways of mashing words 
together in attribute names:

   useMap (traditional usage, though the attribute is really "usemap")
   xml:lang (when in XHTML)

...adding a fifth would make the language even more confusing, something 
that I'm really trying to avoid for HTML5 (I'm trying to standardise on 
the second form in the list above, though the first form is used for 
groups of related attributes like the repeat-* attributes in WF2, and 
would thus make sense for the aria-* group of attributes).

Also the underscore looks really ugly. :-)

Things that are impossible just take longer.   `._.-(,_..'--(,_..'`-.;.'
