A way to unambiguously, compactly and clearly describe a set of @font-face properties. This is implemented as a simple string. For example.

font-style: normal; font-weight: normal;

The possible values for each property are well defined, and a value is required for each property. Values must be a single character. The Font Values Description value and its equivalent CSS value for each property are as follows.
Each property must have a default value, but may have aliases for use when generating a Font Values Description. To maintain unambiguous output, there must be no alias return values.
n: normal (default) i: italic o: oblique
1: 100 2: 200 3: 300 4: 400 (default, also recognized as 'normal') 5: 500 6: 600 7: 700 (also recognized as 'bold') 8: 800 9: 900
a: ultra-condensed b: extra-condensed c: condensed d: semi-condensed n: normal (default) e: semi-expanded f: expanded g: extra-expanded h: ultra-expanded
n: normal c: small-caps
(no properties) => n4 font-style: italic; => i4 font-weight: normal; => n4 font-weight: bold; => n7 font-style: normal; font-weight: 400; => n4 font-style: italic; font-weight: 500; => i5
