Is There a Fifth Marian Dogma?

The big question is, will there be a fifth marian dogma? And a lot of people want that. I don't think there's any biblical attestation to either of them, or any solid historical attestation for them early on. It really does, in a way, represent a fork in the road in terms of two different conceptions of just what are the basic beliefs required for a christianand i am not alone in my concern.
