In fact, in controlled environments, the simplest solution is to write an 
additional specification specifically for that environment that extends 
HTML5 to add whatever preferred versioning feature the authors of those 
documents desire. There's no need to changr HTML5 itself to add this to 
pages restricted to a controlled environment. This gives the additional 
benefit that if the pages ever escape that environment, the proprietary 
additions would be immediately flagged by validators.

This is the kind of information that should be included in the Rationale 
section of the change proposal when it is updated per Maciej's comments.
