My apologies for the lack of timely reply from the chairs on this, and your separately submitted Change Proposal. Here are the responses:

Yes, you should specifically list which points are new.

The decision doesn't take a stand on the relative priority of the generator exception and the requirement for images with role=presentation to also have an empty alt value specified. If you believe this is wrong in the current spec, please file a bug.

The specification is written in such a way that some content is nonconforming but must not be reported as nonconforming by validators. The decision did not attend to this in detail and was not intended to change this. If you think the spec language here should be changed, please file a bug.

You also submitted a Change Proposal for your reopen request here:
http://lists.w3.org/Archives/Public/public-html/2011Apr/0480.html

Here are three points of feedback that should be addressed for this Change Proposal to be considered as part of a reopen request:

1) This Change Proposal seems to go beyond the scope of the issue in a number of ways. The decision was about validation. The proposal includes a number of new implementation requirements, including a new CSS selector. Requests like that can be filed as bugs if desired. However, this Change Proposal needs to be narrowed to the scope of the issue.

2) The Change Proposal does not clearly identify what points (if any) are new information.

3) The rationale section does not appear to include justification of the specific changes proposed, just general commentary about the generator exception.

Regards,
Maciej
