Briefly (I’ll let an RC do detail), valid orders are those that arise from apostolic succession. Valid and licit orders (in the eyes of the RCC) are those that do so, and at the same time are in communion with Rome. Eastern Orthodox=valid and licit. Greek Orthodox=valid.
That’s very brief, and ignores the concept of valid, but illicit (meaning illegal) within the RCC itself (restrictions on actions of bishops, across dioceses, for example). But the broader definition is the one that is pertinent in the discussion of Anglican orders. Even if the co-consecrations of the OC/Utrecht/Anglican bishops, starting in 1932, after the Agreement of Bonn, have infused valid orders in apostolic succession into Anglicanism generally, such orders would not, in Rome’s eyes, be licit. And Rome, AFAIK, has never formally commented on that general subject.
I got no problem with RCs affirming what RCs should affirm. Anglicans might have a different view of the matter (so to speak).
