The difficulty in splitting the spec into layers or shells is that
there isn't consensus on which features are core and which are
esoteric. You're 80 is my 20 was order of the day and highlighted
in Paul Biron's summary of the experience reports.

Which I think, proves my point. Whilst I agree that mixed content is
core - from my perspective it's what XML is all about, but for many
people serialising their data, it's a nuisance and definitely not as
core as xsi:nill.
