Well, that falls within what I meant by warnings.  The only place
English makes an emphasis vs strong emphasis distinction is where the
text is, in effect, spoken.  This is a small subset of the reasons an
author might have for visually distinguishing text.

I don't like that "don't carry any meaning".  For most of the purposes
that text that most authors produce serves, distinguishing types of data
is much more important than how it would be spoken.  It's quite possible
that no page I ever write will ever be listened to, but Web robots may
be running over them all the time, looking for special kinds of text to

My point is not to diminish the importance of alternative-media, but to
point to the importance of descriptive markup for many purposes.
