Requirements concerning a part of CSS not 1.183 + performed by a processor are not applicable, e.g., requirements related to 1.184 + rendering are not applicable to a validator.

The CSS 1.214 + Working Group recommends that experimental implementations of features in 1.215 + CSS Working Drafts also use vendor-prefixed property or value names. This 1.216 + avoids any incompatibilities with future changes in the draft.
