I nearly agree with this, but have two reservations. 

(1)  H1s  are so frequently interpreted as being synonymous with
<region1><h1> ... (as Nat points out) that it's asking for trouble not to
constrain their position a bit more.

(2) One dtd I've been using has two different kinds of heading tag -- a
<head> which can appear *only* at the start of a region, and a <caption>
which can appear anywhere else, but doesn't start a new region. 

The trouble is that it's heard to see how you would tag something as a
heading without there being something following which it is the heading
of - and which therefore is a region.

The only cases I know of are the "pull quotes" which appear typically in
magazines (where you have a sentence or so in big letters splashed down
in the middle of a paragraph to catch your eye) and -- less
persuasively--very low level  newspaper captions where it's just too
much time and trouble to mark every paragraph as a region.
