CSS Validation and php

The validator is telling me that my php code is not valid... By that I mean
when my link contains something like this:

http://www.fireball3d.com/index.php?getnews=1&news_id=1

I get the following error in css validation:

The reference to entity "news_id" must end with the ';' delimiter.

Is this a bug or is my code not valid even though it is perfectly fine php?

Thanks,
Jeff
