Microsoft and PayPal are loose about it. Yahoo is strict. Amazon doesn’t do it at all. What am I talking about? ’m talking about how these sites use and conform to web standards (namely, the latest doc type declarations — DTD — as specified by the W3C.org).

It's not too hard, and we have a transition chart to help you out. It's time to call your DOC and learn why your DT phones home.
