Something about self-issued plus one managed card provider as potential sources?... Obviously it's ideal for there to be no constraints if what one is doing is building a "data-sharing relationship". (I've got another post brewing on what those potential sources could look like.)

An IdP could assemble data from multiple, distribute sources, n'est-cs pas? Of course, the static nature of the infocard is a stumbling block, but it should be possible - in a future version - to implement secure, dynamic managed cards I would think. Think "virtual card," perhaps. -dave I won’t re-read the spec right now, but it seems to me that there’s nothing in the infocard definition that requires that all data encapsulated within a card have the same authoritative source.
