Da_Slayer writes "The w3's HTML group has released the 6th public working draft for XHTML 2.0. XHTML 2 is a general-purpose markup language designed for representing documents for a wide range of purposes across the Web. Meaning it is to be used for document structuring which is why it does not have presentation elements. The draft is located at w3's website. Also they have a FAQ about why you should use XHTML over HTML. It goes into specifics about embedding MathML, SVG, etc... and has links to tools and resources to help convert existing html documents to xhtml. One of those resources is a document on XML events and its advantages over the onclick style of event handling."
