I'm used to ``semantic vs. presentational'' (very common in
web-related circles).

Semantic markup (e.g., emphasis) is part of the meaning of the text,
regardless of the way the text is displayed.  Presentational markup
(e.g., bold) is meaningless out of its presentational context.

There is a close analogy with source vs. object code.  The former is
more portable than the latter.  But the latter is directly usable,
while the former is mostly only used when editing the work.
