Yet the grammar in chapter 4 [F] makes the same mistake:
any : [ IDENT | NUMBER | PERCENTAGE | DIMENSION | STRING
| DELIM | URI | HASH | UNICODE-RANGE | INCLUDES
| DASHMATCH | FUNCTION S* any* ')'
| '(' S* any* ')' | '[' S* any* ']' ] S*;
And the CSS3 Syntax module [S] continues the trend:
any : [ IDENT | NUMBER | PERCENTAGE | DIMENSION | STRING
| DELIM | URI | HASH | UNICODE-RANGE | INCLUDES
| FUNCTION S* any* ')' | DASHMATCH | '(' S* any* ')'
| '[' S* any* ']' ] S*;
