Hi,
If I’m reading the CSS 2.1 Core Grammar correctly, the ED has a few
changes from it that are not noted in section 3.6.
Overall, tehy are all boring details. I’m only writing them up for
completeness.
* [] blocks, () blocks and functions can now contain {} blocks,
at-keywords or semicolons
* Property values, functions and all blocks can now contain cdo and cdc
* Selectors can now contain semicolons
* Selectors and at-rule predules can now contain cdo, cdc and at-keywords
* Anything can contain an unmatched } ] or )
* Selectors are no longer optional in rulesets a.k.a. style rules.
(Although an empty selector is invalid per css3-selectors, it does not
make ruleset invalid per the core grammar.)
(Note: this is with the "preserved token" definition in the current ED.)
I think that the core grammar is more restrictive than it needs to be
(especially the 'any' production). I don’t know if lifting those
restrictions was intentional.
