No, that's not what the specification says. Explicitly, it says:

"Parts of style sheets that can be parsed according to this grammar but  
not according to the grammar in Appendix G are among the parts that will  
be ignored according to the rules for handling parsing errors."

"are among" is essential here, I think.

Now I agree that the specification is not very clear, but it won't become  
more clear if you try to read things between the lines. Given that  
implementors have understood this part of the specification I suggest we  
not change is as that will only increase the chance of introducing errors  
at this point.

(Note that removing DELIM? does not affect whether body { * ; color:lime }  
is handled by the core grammar or not. It isn't. Handling errors in the  
grammar itself has been brought up a few times, but it has not been done  
so far.)
