Then they cannot be enforced and are useless. They can even be harmful
from a REC track point of view.

Yes I am.

Let me give you such an author-related criterium from the HTML4 spec:
authors should not use the class attribute to simulate their own markup.
Fine. "should not" is fine here. But it's not a conformance criterium
because it cannot be one.
The "non-conforming" statement previously mentioned on table layout is
exactly of the same kind: it should be a strong authoring recommendation
but it cannot be a criterium of conformance ; because it's not machine-
checkable, nobody will care and editing tools will be unable to deal
with it. There will also be edge cases where one says it's
non-conforming and others say it is. Chaos.
