Re: TFOOT element

This is a funny detail of how DOMs are specified - HTML and XHTML are 
specified by a DTD, and DTDs are incapable of specifying order of 
elements. The classic example of this limitation is DL, DT, DD. A DL is 
supposed to contain DT and DD elements, but they're really supposed to 
be DT (term) followed by DD (definition), repeat. The DTD can only say 
"There should be DT and DD elements in here, in any order, in any quantity."

So, validating would unfortunately not tell you anything new if order is 
your question. The closest technical definition you could find would be 
the rules in the browsers themselves. You could potentially download the 
W3C's reference browser as a more thorough check.
