Answering my own post: No, I am not correct. I haven't observed [2] which
defines strict rules on how an at-rule may be built (->"any"). Therefore,
only (1) and actually (3) in my original post will parse without a fatal
error.
I noted that in the "any" production [2]:
any : [ IDENT | NUMBER | PERCENTAGE | DIMENSION | STRING | DELIM | URI |
HASH | UNICODE-RANGE | INCLUDES | FUNCTION S* any* ')' | DASHMATCH | '('
S* any* ')' | '[' S* any* ']' ] S*;
the DELIM token is nowhere defined in [css3-syntax]. There is a note in
[3] that DELIM has been folded into CHAR. Should the "any" production
have DELIM replaced by CHAR?
