Thank you for your feedback. The CSSWG has addressed your concerns for 'Issue 6' in the upcoming publication of the CSS 2.1 specification[1]. 

The CSSWG resolved to change the 'Applies to:' to be block containers.

All other issues have been deferred to errata and future versions of CSS.

We hope this closes your issue.

Please respond before 18 March, 2011 if you do not accept the current resolution.
