border color bug when using rgba

Hey there,

I have run in to problem with the css validator located at http://jigsaw.w3.org/css-validator/. My problem is that the validator won't accept rgba values as border color. Forexample:

border-bottom:1px solid rgba(50,50,50,0.8); 

will make the validator come up with the error: 

Value Error : border-bottom Too many values or values are not recognized : 1px solid rgba(50,50,50,0.8 ) 

I have validated the stylesheet code as CSS3.

It looks like a bug in the validator.


Friendly,
