 Previously these have been unsupported, but in this patch we're adding
 support for the tags so that the HTML Processor can process documents
 containing them.

 There was a design discussion about introducing a constant to communicate
 "any of the H1 - H6 elements" but this posed a number of challenges that
 don't need to be answered in this patch. For the time being, because the
 HTML specification treats H1 - H6 specially as a single kind of element,
 the HTML Processor uses an internal hard-coded string to indicate this. By
 using a hard-coded string it's possible to avoid introducing a class
 constant which cannot be made private due to PHP's class design. In the
 future, this will probably appear as a special constant in a new constant-
 containing class.
