This sequence also validates my XQuery expressions :-)

I agree (and my XQuery expressions also).

Having no "h2 without h1" is just another way to say:

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

On the other hand, having a "h2 h4" sequence breaks the following rule:

//h4[let $h4:=self::h4 return
let $h3:=$h4/preceding::h3[1] return
let $h2:=$h4/preceding::h2[1] return
let $h1:=$h4/preceding::h1[1] return
$h1=() or $h2=() or $h3=() or $h1>>$h2 or $h2>>$h3] = ()

So, I am happy to see that my rules work with your examples :-)
