specific structure of the documents may be affected by a change to the
schema. That would include the things you've listed, as well as editor
customizations, browsers, and so forth.
And of course it is possible to change schemas in ways that don't affect
the structure of instances.
It's also important to remember that it's the content of the instances
that ultimately matter, not what the schema says. That is, if the schema
allows A or B or C but the instances never actually have C in them, the
fact that the schema allows it is irrelevant to processors, because
they'll never see a C.
