State:

Product:
HTML Principles/Requirements
Raised by:
Sam Ruby
Opened on:

Description:
Should the new HTML language bear a version mechanism?

HTML5 Specification - Section 8.1.1. "The DOCTYPE"
http://www.whatwg.org/specs/web-apps/current-work/multipage/section-writing0.html#the-doctype

## Research
 
* Karl Dubost's "HTML and version mechanisms" - http://www.w3.org/QA/2007/05/html_and_version_mechanisms.html
* Test case "<!DOCTYPE" - http://hsivonen.iki.fi/doctype/test-quirks.php?doctype=%3C%21DOCTYPE
* Mozilla reference on their DOCTYPE implementation - http://developer.mozilla.org/en/docs/Mozilla's_DOCTYPE_sniffing

## Proposals

* IE 8 Versioning Scheme
   * "IE8 versioning snowstorm" - http://www.w3.org/QA/2008/01/ie8_versioning_snowstorm.html
