We Anglicans tend to be disgustingly ignorant on this subject.
For no particular reason, I found myself wondering, with regard to the Military Ordinaries they have in the RC Church: are Chaplains incardinated into their Ordinariates? Whom do Ordinariate clergy mention in the Canon?
By the way, a quite friendly RC blog gives a list of 'rites' that clergy in Pope Benedict's Ordinariates would be restricted to. But surely, these structures and their clergy will be part of the Latin Church. So, surely, they will have access to the provisions of Summorum Pontificum?
