Oops, that should have been tbody and tfoot. Good catch.

Good catch as well.

It gets very confusing if you talk about tags being followed by elements. 
The "tags" are just unstructured characters in a stream. The "elements" 
are in a DOM. So the presence or absence of tags IMHO has to be given in 
terms of the elements in the DOM.

But at any rate, fixed, by saying that <tbody> can't be omitted if the 
preceeding element's end tag was omitted.

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