Valid XHTML?

People tend to stick a "This is valid XHTML" logo on their site (probably a trend today?), however in 99% of all cases the page does not validate as a standard XHTML document. Sad They even used to put a link on the page pointing to http://validator.w3.org/check/referer and if you click to check, you get at least half a dozen errors (or warnings in the best case). Where's the sense in that? Shock I've got that link too, but pages on this site truely validate as XHTML Strict. Tongue
