Thanks for pinging me. I have now reviewed the changes, and I agree that
they fully address the issues I raised.

I have taken this opportunity to review the entire draft, and it looks
very good to me.

I only have two comments on the whole document:

* There is one issue left in the draft:
"Issue 1: This needs to specify what to do if rule is the empty string,
if it contains more than one CSS rule, or if it contains garbage after
a valid rule."
Unless there are backward compatibility concerns, I would say we should
specify that under such conditions SYNTAX_ERR must be thrown. I am not
strongly attached to this if someone has good reasons to prefer
something else, but I think it is a simple and natural answer to the

* "The conditionText attribute, on getting, must return the result of
serializing the associated condition."
We had a discussion at the San Diego face to face about what the
serialization of the supports_rule should look like, but I cannot find
the conclusion we had reached in this draft. Has it been written into
another document? Is it voluntarily left unspecified at the moment? I
would not have a problem with this draft moving forward without
serialization being specified, or with reopening the question, but
since we had discussed it, I wonder where it went.

Best Regards,
