No. The page author may use any style he or she desires. There are more
ways to distinguish headings than size (what about colour, as mentioned in
another of those mutually-contradictory recent messages?). You cannot
uniformly declare there are *no* cases where you do *not* need to
distinguish headings from text in terms of size. BTW, how *does* a size
difference work in Braille?

Jim:
Braille has limited formatting capabilities. See information below. Most
braille translators will import HTML and apply appropriate braille
formatting to structural tags (Hx, p, ul, ol).

Headings

     There are three kinds of headings in braille: major headings, minor
headings, and paragraph headings.
     A major heading is centered, with a blank line before the heading,
and a blank line after it. Some braille groups do not put a blank line
after a major heading. Technically, this is a violation of the rules for
braille.
     A minor heading is blocked to cell five. This means that the heading
starts on the fifth cell of the line. Any runover also starts on the fifth
cell of the line. Usually, there is a skipped line before a minor heading,
but not after a minor heading.
     A paragraph heading is a line or phrase in italics (or some other
emphasis) that labels a paragraph and is immediately followed by text on
the same line. If this is done in inkprint, do the same in braille, using
italics.
     Braille rules require that there be at least one line of body text
after a heading or headings on the same page. If there is not enough room
on the page for the heading(s) and a line of body text, then the
heading(s) need to be postponed to the top of the next braille page.
     Before you start a braille project, you need to structure the
document. You need to analyze how many levels of headings there are. You
need to decide which of these should be done as a major heading, and which
should be done as a minor heading.

Capitalization should match that of the inkprint version (all, initial,
sentence). Note: HTML import will use the case and text content of the tag
(e.g. <h1>) and will ignore any style (linked, embedded, or attribute) (e.g.
uppercase) that may be applied to the tag.
Text may also include emphasis (bold, italic).
