About sections ß6.1 and ß6.2, is there a difference between:

1. a declaration being 'invalid' (and thus being ignored by the parser 
to allow old-style fallbacks)
2. being 'not supported' (resolving to false in @supports)


Iím thinking in particular of 6.2ís comment on values that might be 
valid in a spec but the UA "do not have a usable level of support for".

I think that the two notions should be the same, and that 6.2ís comments 
should apply to both. CSS 2.1 was less clear on this subject, only Iím 
not sure that itís within css3-conditionalís scope to affect the parser. 
Should this last part go into css3-syntax?
