Agreed, but here we are...

Nevertheless... the color wasn't a css3-color either.  And no, for HTML 
attributes browsers don't necessarily use css3-color.  Certainly Gecko 
doesn't.

That would break standards pages that depend on the correct HTML4 
handling (and they do exist, by the way).  We don't want to be going 
there, I don't think.

Note that the current http://www.w3.org/TR/html5/tabular.html still has 
zero rowspans (though not zero colspans for reasons that escape me).
