The problem here is that both your plans defeat one of the main precepts
of CSS: That content and presentation should be seperated. So CSS should
not concern itself with the actual content presented; only the manner in
which it is presented.

Furthermore, if you ask people to write their content twice (e.g. once in
plain text, and once in IPA), they will not do it.

One possibility might be to consider having some way to load the actual
HTML page based on the presentation style present. So you could have one
HTML page in ASCII-IPA, with only aural styles, and another in plain
ASCII, with only visual styles, and possibly without some surpurfluous
content.

In many circumstances, authors may wish to customize their presentation
based on the method being used to convey content to their readers. Or if a
site expects to have a large blind audience they could translate their
pages into IPA for better screen reading. But this behaviour should be
OPTIONAL. By default, all content should be accessible to everyone.
