Is there some other change in ODF 1.2 that we can always rely on being
that there would distinguish a file from pre-1.2 versions, such that we
could tie validation to that?
In RELAX NG, you can do this:
start = ODF-1.1 | ODF-1.2
ODF-1.1 = element foo { element bar { text }, attribute version { ID }?
}
ODF-1.2 = element foo { element bar2 { text }, attribute version {
"1.2" } }
In that case, if there was a bar2 child of the root, the version
attribute would be required.
