A2: SGML declaration?

On 9 October 1996, the ERB will vote to decide the following question.
A non-binding preliminary vote indicates the ERB is now leaning to Yes.

A.2 All or virtually all the information provided by a normal SGML
declaration will be fixed for all documents; no SGML declaration will be
necessary.  (Possible exception:  character-set information may vary
document to document, but will be conveyed in other ways.)  (6.2.3)
