[last call] Unambiguous parsing

Technical/substantive issue?

The current requirement fo unambiguous parsing is impossible to meet -  
there are always multiple ways of parsing any data.

Instead I suggest the old wording of "conforms to formal published  
grammars".

This makes it feasible for User Agents to recognise the content and parse  
it either according to the rules for such grammars, or in cases where it  
is necessary (such as HTML) to use specifically adapted parsing techniques.

cheers
