one comment about icon/link of valid css and css3

Hi,

Thanks for your work. I would like to know if there is any way to validate
against css3 using the link, provided in the icon:

<p>
    <a href=*"http://jigsaw.w3.org/css-validator/check/referer"*>
        <img style="border:0;width:88px;height:31px"
            src="http://jigsaw.w3.org/css-validator/images/vcss"
            alt="¡CSS Válido!" />
    </a>
</p>


something like this:
http://jigsaw.w3.org/css-validator/check/referer*&profile=css3*

I know that css3 is still not approved, and css 2.1 is the current standard,
but I would like to start following it as soon as possible and validate my
css agaisnt it (as long as some serious browsers support part of them
already), not sure if there is another icon/link for it (I cannot find it
following FAQs).

Thanks for your help and time. Best Regards,

Frank Sebastià
