RE: [CSS21, section 11.1.2] specification on clip property can be and should be improved

Hello Gérard,

The CSSWG resolved not to make these changes to the CSS 2.1 specification [1]. We will be reevaluating this issue for errata and future versions of CSS.

Please respond before 18 March, 2011 if you do not accept the current resolution.
