Properties are part of rule sets, which are defined in Chapter 4:
  http://www.w3.org/TR/2004/CR-CSS21-20040225/syndata.html#q10

Descriptors are part of @font-face rules, which are not in CSS2.1, but
are defined in Chapter 13 of CSS2:
  http://www.w3.org/TR/1998/REC-CSS2-19980512/fonts.html#font-descriptions
or in css3-webfonts:
  http://www.w3.org/TR/2002/WD-css3-webfonts-20020802/#font-descriptions

This doesn't seem particularly unclear to me, although it's perhaps
worth emphasizing the distinction in the definition of all the
descriptors, since they're rare.
