The Apostolic Constitution Anglicanorum coetibus says the the CCC will be the doctrinal standard of the Ordinariates. Naturally, therefore, it is being used in the 'formation' of Ordinariate clergy. I know of no other grouping within the Roman Unity which, apparently, has its own doctrinal standard; not even the 'uniate' Churches with their sense of a distinct theological - as well as liturgical - inheritance. Everybody else is expected to adhere to the doctrine of the Magisterium, in accordance with the the degree of solemnity with which a particular matter has been proposed. For example, decrees of doctrinal Ecumenical Councils and ex cathedra pronouncements of the Roman Pontiff are to accepted as a matter of divine faith; other pronouncements by the teaching organs of the Catholic Church are to be given lesser degrees of assent or 'religious respect', according to their respective status.
I contend that the status given to CCC in Anglicanorum coetibus is not in fact different from the status it has been declared to have in all the other particular churches in full communion with the See of Peter. In other words, I do not think that it imposes extra dogmas upon Anglicans which are not imposed upon others; and I do not think that it imposes a lighter obligation of dogma upon Anglicans than upon others. There are things in CCC which are proposed as infallible teaching to be received with divine faith; but they are not thus imposed by the authority of CCC itself. I have in mind, to give obvious and random examples, the Nicene Creed and the decrees regarding the Sacraments at Trent and the dogma of the Assumption. These are to be received as infallible because of the authority of the organ which first imposed them, not because of the authority of their repetition in CCC. Other things in CCC lack the authority of an Ecumenical Council or a Roman Pontiff speaking ex cathedra; these are to be accorded the same respect as they enjoyed anyway and already by virtue of their standing, whatever it was, in the Church's Magisterial teaching ... which may be lesser. In other words, not everything in CCC is proposed with the same force and authority. Cardinal Ratzinger himself wrote "The individual doctrines which the Catechism presents receive no other weight than that which they already possess".
