[Bug 5202] Part 2 Incompatibilities

I think that an invalid schema document becoming valid in the next release is a
change that everyone expects and no-one worries about: that's the way languages
move forward, and it belongs in our "list of changes since 1.0" rather than our
list of incompatibilities. 

But I think that an invalid instance document becoming valid in the next
release is worthy of comment, because it allows documents through the filter
that the receiving application might not be able to cope with, and might be
trying to protect itself against; it also means that a sender who is validating
outgoing documents using Schema 1.1 might be transmitting stuff to a recipient
who will validate it with Schema 1.0 and find it to be invalid.
