I don’t understand.  How is it worse to provide authors an opportunity to specify the encoding they have used, even though they may specify wrongly, than it is to deny them an opportunity to specify the encoding at all?

How is it a worse or more impactful mistake for an author to include an incorrect encoding tag than it is for them to use an encoding different from some small set that you are prepared to accept?

Can you expand on that?  I don't follow you.

I see no way to write the specification that can eliminate all possibility of encoding-related errors.  None.  All we can do is choose which errors are possible.  In so doing, there are a lot of competing factors consider, such as likelihood of various errors to be committed, coverage and robustness of the resulting spec, implied responsibilities of various parties, user convenience, and cultural sensitivity.  I think when James's summary is ready it will help us sort through all that.
