A20: comment syntax in XML?

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.20 XML will retain the notion and syntax of comments (= 8879's
'comment declarations') (7.6, 10.3), but comment declarations will
contain at most one comment:  comments will take the form '<!>' or else
will begin with '<!--' and end with '-->' (no space allowed), and may
not contain '--'.

(Editor's note:  the ERB did not explicitly discuss empty comments;
the consensus may extend only to the <!-- ... --> form, and not to
keeping <!>.  -CMSMcQ)
