All these examples also work with my rules :-)

Neither of my expressions say that explicitly. However, by proper 
deduction and combination of my rules, you will implicitly obtain that 
there is no other possibility. So, yes, the first header in the document
must be an h1 (or there should be no header at all) if tests 37-41 should 
be followed. There is no explicit rule for that, but it is derived from 
tests 37-41.

That's why I did not include a rule saying:

count(//h1) <= 1
