Also, if you are referring to the fact that a comment seems to occur
*inside* a token:
You should be careful mixing chapter 4 (the forward-compatible, core
grammar) with appendix G (a more restrictive grammar that is closer to
what is actually meaningful in CSS level 2).
When chapter 4 says that comments can occur "between tokens," it means
tokens of the core grammar. The "!important" in the appendix is in fact
made up of two core tokens, DELIM ("!") and IDENT ("important"), and
thus comments can occur between them.
So, no, this is not an exception.
