An unrecognised format passes rather than fails
The rule
Normative: this is the rule

formatname the implementation does not recognise passes, so a schema written against a richer vocabulary never blocks a node from running.
Rule identifiers are permanent and are never renumbered. Each implementation publishes its own standing against these rules; this specification does not.spec 1.0-draft · CFG-12 · changed in spec 1.0
