I don't think this is correct. Isn't the problem here the character set
demon that haunts us continuously? Terry is absolutely right that things
like title and subject will require italics and superscripts... look at
the Chemistry literature, for example.
And indeed, I *DO* want displayable metadata... I just don't want it displayed
as a matter of course by browsers.
But I think we need not resolve the fine details at the outset... the
whole idea is to quickly put in place a convention that will allow us
to experiment without splattering the users screen with ugly constructs.
