The schemas that could change (i.e. not the SAML ones) are backward
compatible, but not forward. A valid configuration on 2.0 is guaranteed to
validate against the 2.1 schema but not vice versa. So, yes, if you're
packaging the schemas separately from the SP itself, you need to make sure
that a 2.1 SP is using at least the 2.1 schemas.
