[css3-fonts] Editorial: @font-face never uses the family name in the downloaded font data

Hi,

In §4.2 Font family: the font-family descriptor:

> This descriptor defines the font family name that will be used in all
> CSS font family name matching, overriding font family names contained
> in the underlying font data.

This seems to imply that the family names in the downloaded data are 
used if the font-family descriptor is not provided. But this is not the 
case according to §4.1:

> @font-face rules require a font-family and src descriptor, if either
> of these are missing the @font-face must be ignored.


§4.2 could be re-worded with something like "font family names contained 
in the underlying font data are never used."

Cheers,
