Construct a copy of the specified `other` namespace registry using the (optionally) specified `basicAllocator`. For a given URI, the results of calling `lookup` by URI will produce equal results for this object and for `other`. For a given integer ID, the result of calling `lookup` by ID will produce different pointers that compare equal using `strcmp`.
