This isn't correct. While the |deg| unit identifier is not required (and 
apparently forbidden), your syntax has the following errors:

1. The saturation and lightness arguments are percentages on a range 
from 1-100, not 0-1.
2. Unlike other CSS values, the percentage (|%|) unit identifier is 
required even for values of zero.

(I don't know where the spec says those things though; for some reason, 
CSS3 Color seems to be lacking as far as syntax productions.)
