Modifying Dreamweaver to Produce Valid XHTML

Credit to Lee Aplin for finding this link, which outlines how to tweak Dreamweaver to produce XHTML (for those of us using older versions than MX 2004). Why should we produce XHTML? Two reasons: accessibility (so people with disabilities can access your content) and compatibility (so your content can be viewed on anything from a mobile phone to a PDA). Check out Wikipedia's definition of XHTML for more.
