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.
