[e] (0) The giant clean-up of 2013. Improved internal consistency, adjusted section order to make more sense, started a move away from abusing title='' for cross-references, fixed minor typos, cleaned up some dangling TODOs, very minor typo fixes, dropped some obsolete comments, un-commented-out minor things that had previously been commented out for reasons that no longer apply, etc. No normative changes.
Affected topics: CSS, Canvas, DOM APIs, HTML, HTML Syntax and Parsing, Microdata, Offline Web Applications, Rendering, Security, Video Text Tracks, Video and Audio, WebSocket API, Workers
