True, but calling the property "font-index-or-size" didn't seem very
attractive:-)

My `corresponding' shouldn't be taken too literally. It is perfectly
OK to map Netscape's font #3 to medium. In fact, like you, I would
think it strange otherwise.

#6 would be xx-large, #7 would then be an unnamed size that you can
only reach as a relative size, e.g., with font-size:+3 (assuming the
parent has medium).

CSS's x-small and xx-small may both be mapped to #1. The spec says:
"the UA should take the quality and availability of fonts into account
when computing the table."

The intention of this is that it is safer to ask for medium than for
10pt, since the browser can then choose the best size. Because of
screen resolution and other factors, medium may turn out to be 10.7pt,
or something else that the author could never have guessed.
