Yes.

Yes. I must apologise for not saying what I was thinking earlier. Most
of the discussion focused around wording the HTML 2.0 document such
that the SGML declaration inference mechanism became clear. I think
Francis and I went back and forth a little because I did not want any
commitment in HTML 2.0 until my proposal was aired.

The translation from the document character set to the system
character set is not specified by SGML. Hence, this is system
dependent.

Yes, I spent a lot of time trying to avoid anyone making a commitment
here!
