Political views as well as some technical.

Clear majority though? Option of deprecating.

     Multiple requests for some set of entities.

A small number of real examples given.

     Not seen on this thread Liam? Unless you mix it with your 7?
     Keep separate?

I'd sum that as clear desire, syntax to be agreed?

Again a minority view as expressed on this thread.

Majority disagreement IMHO.

From my notes:


Namespaces. Clear desire to simplify, MK suggestion gained most support.

-- within comments.  Nested comments. Alternate syntax for comments.

Backwards/forwards compatibility? Any XML1 should be XML 2 and vice
versa.  Small majority favoured a tranform to get from SXML to XML 1.0.
Related, "don't break the existing toolchain" Many expressed a
preference for a real break, with many new features. Features classified
as breaking|non-breaking

Graph rather than tree. Minority view.

Clear requirement for entities "in some form" macros might be a clearer
description? Not necessarily as part of an internal DTD.

More lax whitespace treatment. Minority but supported. Or choice on
white space treatment

Vague, but clear message that simplicity is a real requirement. 

Links. Vague but supported call for better linking.


Even more vague. Learning lessons from JSON. Simplicity without loss
of XML essential features. Data typing as a benefit ( supported feature)
