The correct use of the <H> tag in PDF depends on valid nesting of the tag tree. For this reason (among others) I do not believe that <H> is as well-supported by today's AT as are enumerated headings (corrections are welcome).

No-one's "rules" should require the use of <H> over <H#>; that's absurd. H2, H3, etc. are *certainly* safer than <H> in terms of AT support.
