You selected some schema to test, so yes, maybe it passes. It's not a
proof of anything. Run with either applicable bindings (the one which I
commented about) or with all of them.

If you did it, you would see the check will fail. The bindings would
report error. There is no need to engage reviewers if bindings find the
errors for you, right?

Nodes you added here are not allowed.
