After being informed that things are defined in terms of CSS3 Values & 
Units, this seems more clear. From Section 4.2.4 HSL color values: "This 
angle is so typically measured in degrees that the unit is implicit in 
CSS; syntactically, only a <number> is given." Since |<angle>| is its 
own type, |deg| is apparently excluded.

Okay. That's pretty unintuitive, but makes sense. (I thought this was a 
bug in Firefox until I found that four other browsers agree.)
