Comments and CDATA sections will certainly be near the top of the list
for a level-two SAX, if people decide that we need such a beastie.  In
the mean time, please remember that the DOM models everything that
_can_ be represented, not everything that _must_ be represented.

There will probably end up being a core set of information that every
DOM builder must provide, but I'd expect that much of it will be
optional.  A DOM builder for a simple processing tool won't want to
waste nodes for information that it doesn't need (such as internal
entity boundaries).

I think that the chair of the DOM WG, Lauren Wood, reads this list;
perhaps she can comment or correct any mistake that I might have made
here.


All the best,


David
