Intenzionalità, normatività e riferimento

According to Marconi, the idea that TwinEarth experiments undermine referential competence presupposes the thesis that reference is objective. Yet this undermining depends on whether this thesis is meant to regard the objects of this relation rather than the reference relation. Is it possible to have both referential competence (as regards full-fledged objects of reference) and a non objectivist reference relation? At first blush, one may answer this question affirmatively by committing to intentionalia which are possible entities. Yet a better answer is to conceive the reference relation in robustly normative terms.
