I mean not in what is today section 12.

For example, where the spec says "Let the current column be the first col 
element child of the colgroup element". Why is that not ambiguous?

Right at the top of the spec it says "Except where otherwise stated, all 
elements defined or mentioned in this specification are in the HTML 
namespace ("http://www.w3.org/1999/xhtml"), and all attributes defined or 
mentioned in this specification have no namespace.". What I'm confused 
about is why this is enough for part of the spec, but not other parts of 
the spec.

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