Vendor specific extensions

Hi all,

My apologies if the following has already been said here, as I  
couldn't find it in the archives:

In CSS2.1, vendor specific extensions were formalized: http:// 
www.w3.org/TR/CSS21/syndata.html#q4, and they have been included in  
CSS3 as well: http://www.w3.org/TR/css3-syntax/#vendor-specific.  
However, when parsing the style sheet of one of my websites  
(css3.info) I find that these vendor specific extensions give errors.  
This doesn't really encourage testing of these extensions, which are  
mostly implementations of w3c drafts that have not yet reached CR  
status.

Is there some way to fix this validation? Or is any such feature  
planned?

Regards,
Joost
