Same level in what sense?

Well, there is one way: nesting <section>s.

I don't think it's "obvious". Indeed I don't think it's true -- while I 
could see an argument for consistent styling of the species, I don't 
consider them to be the same level. In the outline above, I consider I and 
J to be different levels from F and G.

There are subheadings in HTML5. See the <header> element.

And there is a way to skip levels; the <section> element.

Are those solutions satisfactory, or do you still want the rank of 
<h1>-<h6> to imply missing sections?
