I agree with option 3 only. Our registrar client systems use a validating
parser for registry responses, and it's always a major pain to fix issues
when unexpected XML namespaces start showing up.

That being said, for some registries (such as Afilias) it seems to be a
challenge to even produce schema-compliant server responses when it comes
to the standard EPP RFC schemas.
