doctype rule

Hi ....If it is not too much trouble to ask what this error means when I try to validate my CSS:

org.xml.sax.SAXException: Please, fix your system identifier (URI) in the DOCTYPE rule. 
My doctype is currently set as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.W3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

If you could direct me as to where my problem lies I would be most grateful.

Regards,
