CSS1 clarifications?

Yes, we have identified some "issues" in CSS1 and will make sure these
are "clarified" in CSS2. Also, we plan to publish a separate errata
sheet for CSS1.

The most serious problem we've found is that a number of properties
declare that percentage values refer to the width of the parent
element. (E.g., see [1] for an example). This is only true if the
parent element is a block-level element. A better text would be to say
percentage values "refer to the youngest block-level ancestor".

Please publish them on this list. Even if they don't quite qualify as
ambiguities in the eyes of the authors -- most reported problems don't
-- your reports will help use improve CSS2.
