I guess the main problem is that I am not really familiar with lex /
yacc. The situation with the attribute is a bit different from string
literals though:

1) Inside a string literal, everything is just text. The inside of the
attribute still should be tokenized.

2) [ is atoken that has many uses in C. We don't really know we're in an
attribute while in lex, that knowledge is only there yacc.
