Even if this assertion is correct, I don't think it makes for an  
appropriate design principle. None of the principles so far are of  
the  form "HTML must not support feature X". It's hard to see how  
such a principle could ever be justified in general, unless feature X  
intrinsically violates the other principles. (For example, full read/ 
write filesystem access would violate the security principle, but for  
that reason I don't think it's worth mentioning.)

It seems entirely appropriate to me for "A language evolved from  
HTML4 for describing the semantics of documents and applications on  
the World Wide Web" and "Document Object Model (DOM) interfaces  
providing APIs for such a language" to satisfy the very common  
application use-case of an immediate-mode drawing area.

So the charter seems to allow (arguably even encourage) such a thing.  
Do you have any argument against?

Maciej
