I am afraid you did not understand me. I agree with your example (it is 
perfectly OK), but I did not misunderstand tests 37-41.

Please, take notice that I said that "there should be at least one h1 
somewhere before every h2":

//h2[preceding::h1 = ()] = ()

instead of "the previous header of every h2 should be a h1", which would 
be the following expression (which I also disagree with):

//h2[let $prev := preceding::(h1|h2|h3|h4|h5|h6)[1] return $prev = () or 
node-name($prev) != "h1"] = ()

This is another example of why I consider XQuery expressions useful for 
avoiding misinterpretations. :-)))

The same applies for h3-6. Your sequence validates all my XQuery 
expressions, so it is OK.

Best regards.
