From the site of the SSPX. Here is the salient parts, as far as I can tell. Read the whole thing there.
[...]When I stated on August 15 of this year that we were in agreement on the fact that we did not agree about the Second Vatican Council, I also made sure to explain that when it comes to dogmas, like the doctrine of the Trinity, we are quite obviously in agreement when we find them mentioned in Vatican II. One sentence must not be taken out of its context. It is to the great credit of our theological talks that they seriously examined and elucidated all these doctrinal problems. The joint press release by the Vatican and the Society [Interesting. The press release I saw seemed to come only from the Holy See.] announced that a doctrinal document was delivered to you and that a canonical solution was proposed to you. Can you give us any particulars?
This document is entitled “Doctrinal Preamble”; it was handed over to us for in-depth study. Hence it is confidential, and you will understand why I say no more about it to you. However the term “preamble” does indicate that acceptance of it is a preliminary condition for any canonical recognition of the Society of St. Pius X on the part of the Holy See.
Q: On the subject of this doctrinal preamble, to the extent that this does not concern its confidentiality, can you confirm that it contains, as announced in the press release, a distinction between what is de fide [essential to the faith]—to which the Society fully adheres—and what is dependent on a pastoral council, as Vatican II itself claimed to be, and thus could be subjected to criticism without calling the faith into question?
FELLAY: [...] Today, for the sake of objectivity, I must acknowledge that in the doctrinal preamble there is no clear-cut distinction between the inviolable dogmatic sphere and the pastoral sphere that is subject to discussion. [...] At the same time, it leaves open to legitimate discussion the examination and theological explanation of individual expressions and formulations contained in the documents of Vatican Council II and of the later Magisterium.” There you have it; no more and no less.
Q: [...] … there has been talk about a [personal] prelature rather than an ordinariate; it this correct?
FELLAY: As you correctly note, this canonical status is conditional; only later on will we be able to see the exact modality of it; it still remains a subject for discussion.
Q: When do you think you will give your answer to the proposal in the doctrinal preamble?
FELLAY: [... ] But I can assure you that our decision will be made for the good of the Church and of souls. Our Rosary Crusade, which continues for several more months, must be intensified so as to enable us to obtain, through the intercession of Mary, Mother of the Church, the graces of light and strength that we need more than ever.
I am all in favor of that Rosary Crusade.
