W3 Organization XHTML Recommendation
The W3 Consortium is the definitive source for the specification. They also have a CSS validator and an XHTML validator which will scan your page and validate it's compliance to CSS or XHTML standards.
W3 Organization Validator Service
Validate your pages against the W3 Organization HTML, XHTML, and CSS standards. If your pages pass, you then have permission to use a logo on your page that signifies compliance. However, if you have developed your pages with FrontPage, they will not validate until you add the correct !DOCTYPE tag as the first line of the file.
