Funnily enough, some of these pages are nearly valid HTML5. This one, for example: http://home.mcom.com/docs/product/netsite.html http://home.mcom.com/docs/product/netsite.html The only issues are a missing doctype and a couple of stray tags. This is because (parts of) the site were written before Netscape went wild with extending HTML.
