Call it XHTML 2.0 or something like that. Calling your experiment HTML6 is a terrible idea. Terrible because not only it disrupts completely on how HTML matured, but also because there won't be any more HTML versions from now on; HTML is now a living versionless standard. Sorry, my intention is not to just bash your idea. I personally disliked it because it resembles xml, something that I learned to hate. But that's me. But please, don't call it HTML6.
