[css3-values] angle unit and 0

In css3-values [1], the text implies that "azimuth: 0" is invalid as units 
are mandatory (unlike length units (section 5)).
However, in CSS21 [2], it says
Like for <length>, the unit may be omitted, if the value is zero: '0deg' 
may be written as '0'.
Should css3-value say something there, either the same thing, or that it 
is deprecated.
