The W3C HTML Working Group has published our first “public”[^htmlwgpublic] document: HTML Design Principles. The Design Principles are like a project specification in English prose and are meant to keep us on track when discussing issues with the specification. One the thing to keep in mind when reviewing the current HTML 5 specification is that it is really targeted at user-agent implementors (read: browser manufacturers) but there is an effort in progress to address the web author’s point-of-view. If you are new to (x)HTML 5 you might want to take a look at the HTML 5 differences from HTML 4 document Anne van Kesteren put together a while ago.
[^htmlwgpublic]: I say “public” because everything we’ve done (emails, IRC conversations, teleconferences, face-to-face meetings, document revisions, wiki collaboration, etc) since March 2007 is out in the open for people to look at.
