[whatwg] When should a script be parsed

I am in the process of setting up a test page (informal), from which I 
intend to make real tests and submit bug reports to Webkit, Mozilla, 
Opera, etc.


It is not finished yet. It does nut run at all in MSIE...

But a few things are noticeable:

Webkit based browsers happily tries to parse scripts after the following 

  <script language=javascript1.6">
  <script language=javascript1.7">

Even though neither Safari nor Chrome support those JavaScript versions. 
And it is not a matter of bugs, but lacking implementations.

No browser runs script specified with:


A. Should not the spec mandate that a browser must support a certain 
version of JavaScript if it tries to run it?

B. Should the spec mandate that a browser must run a script that it de 
facto supports, e.g. ecmascript 3 in Firefox?

I think neither issue is clear today. Perhaps this is outside the scope 
of HTML 5?
