Two "easy test" answers in explaining compatibility to a "newbie"
- hopefully not too simplistic or optimistic, and not necessarily
complete:
1. If a new XML has a broad enough foundation set, then much of
what exists should be translatable (but maybe ugly).
2. If the new XML is indeed extensible, then, for a module
(whatever that is), it should be possible to specify a syntax (i.e. a parser
that produces infosets) and a semantics (i.e. a standard or process that
recognizes and can handle the resulting infosets).
Clearly compatibility is a driving requirement, and these and other
considerations are fundamental and necessary. Compatibility should dictate
that all that is possible with at least two commercial browsers is
supported in some manner. Simplicity is an immediate goal
for developers. Browsers are stuck with the past, but goals of
extensibility and long term simplicity are useful for browsers.

Easy test, how easy would that be to explain to a
newbie? Surely if you want XML 1.0, use it. The new work should remain
new and kept that way?
Certainly worth an explanatory section saying
what is/isn't backwards compatible.
