Ah, sorry.  I was looking at the ::first-letter restrictions, and
furthermore was looking at a w3schools page because it was first in
the search results.  It listed clear as applying, which is obviously
wrong now that I look at CSS2.

If we *don't* allow it to match across element boundaries, then is
there a good reason for the restrictions?  I don't believe there is.
I'm not seeing anything wrong with, say, turning an arbitrary span of
text into a display:table-cell as long as it can be wrapped in a
single pseudoelement box.  There is significant power to be gained by
allowing the full suite of properties on ::text, which is a very
strong argument for not allowing it to cross element boundaries.

I gave an example earlier of a site header with specially-formatted
text that I had to do with multiple meaningless spans.  Being able to
use ::text to select, size, and position those would be very helpful.
My company's main site, www.igofigure.com, has essentially the same
situation with its site header.  I really want to be able to position
these things, and can't do that if we apply ::first-line restrictions.
