By my reading of the proposals, yes (both in the sense of 
inline/text-level elements and elements styled "display: inline;").

Why would you expect a validity error? Your proposed use of it is valid 
syntax but utterly incompatible with how it should work.

It will cause problems if browser developers ever implement W3C's 
proposals. If your suggestion was widely implemented, it would make 
implementing W3C's proposals impossible. This is practically a case 
study of why only designated extension points (like class and meta and 
vendor-specific prefixes) should be used for extensions.

I'm not sure what you mean by "default to CSS2". Popular browsers do not 
branch their CSS-handling code for different CSS levels; most implement 
a mixture of features from different levels, including CSS3 proposals.
