Vatican II has both Pastoral and Dogmatic documents. The documents on the the Church, and Divine Revelation are dogmatic. The documents on the Formation of Priests and the Modern World and the like are Pastoral. The documents on Religious Liberty and Ecumenism are a mix of dogma, prudential policy, and pastoral guideance.
Dignitatis Humanae as such can not be a dogmatic pronouncement as it contradicts the dogmatic pronouncements in Quanta Cura.
