Sorry, I got the impression that font-size included accents from a
number of members of this mailing list, not from the spec. I resorted to
this mailing list because the spec wasn't very clear. I would appreciate
it if you would update the spec to include some clarification saying
that the font-size relates to the "em square", which is used by the font
designer as a guideline, and that certain glyphs may actually bleed
outside their em square. (Or words to that effect.)

But does it also plainly indicate the relationship between ascent and
font-size? If so, where exactly?

Sorry, I didn't really know what CSS2 expected of me in this area. I
would like to get Mozilla to pass Baron's font-size test:

  http://www.fas.harvard.edu/~dbaron/css/fonts/sizes/

According to the following document, Mozilla fails the font size test:

But I'm starting to think that the Windows version of Mozilla handles
font-size correctly. David?
