[temp.spec.partial.match] does refer to [temp.spec.partial.order].
Also note that the definition for ambiguity is in [temp.spec.partial.match],
not in [temp.spec.partial.ordering].

It is possible to publish a Technical Corrigendum for the current
standard, which is C++23. Versions before that are withdrawn,
and changing them is not possible.
WG21 has never published a Technical Corrigendum, and given the
three-year cadence in which we publish standards, it's unlikely
we'll ever do so. (The next standard will arrive too soon to
make a Technical Corrigendum worth the effort.)
