What about VideoObject / Course / HowTo / Recipe / Event?

Course, HowTo, Recipe and Event have embedded profiles in this checker; VideoObject does not. A type outside this registry can still be valid Schema.org vocabulary. With Auto-detect it receives structural checks only; selecting a known expected type can apply that fallback profile. Read mismatch warnings instead of treating the result as vocabulary approval. The available dropdown is not a list of current Google search features. Check the current documentation for your content and intended consumer rather than assuming that a profile, sample or passing score establishes feature support.
