Re: structure or presentation?

The boundary between content and presentation is somewhat fuzzy.

It is generally asserted that <strong> is content markup while
<b> is presentation.  If, however, "b" is perceived as standing
for "bold" -- parallel in English meaning to "strong" -- rather
than "boldface" -- a font style, then the distinction between
<strong> and <b> disappears.

While "center" does suggest presentation, a content-level container
for, say, inline, paragraphs, and lists, called "display" would by
default, in my view, suggest the same screen application handling as
"center".  A way to present "display" in an audio stream, for example,
might be to switch voice gender.
