Proposed resolution:
This wording is relative to N4762.
Change [meta.trans.other] as indicated:
-3- Let:
(3.1) — CREF(A) be add_lvalue_reference_t<const remove_reference_t<A>>,
(3.2) — XREF(A) denote a unary
classalias template T such that T<U> denotes the same type as U with the addition of A’s cv and reference qualifiers, for a non-reference cv-unqualified type U,(3.3) — COPYCV(FROM, TO) be an alias for type TO with the addition of FROM’s top-level cv-qualifiers. [Example: COPYCV(const int, volatile short) is an alias for const volatile short. —end example]

[meta.trans.other]/3.2 states:
[Let] XREF(A) denote a unary class template T such that T<U> denotes the same type as U with the addition of A’s cv and reference qualifiers, for a non-reference cv-unqualified type U,which is nonsensical: a specialization of a class template cannot possibly be a cv-qualified type or reference type. XREF(A) must be a unary alias template.
