An apt description. No one is really arguing against the desirability of a citation in a biography article (especially a BLP), confirming attendance at a particular educational institute. However, some (myself included) would disagree with the view that such citations are or should be mandatory for bluelinked names in the "notable alumni" section of the educational institute itself. I think we might all be able to agree that any redlinked/unlinked names should have a citation to at least demonstrate that that person is notable enough such that a Wikipedia article about them should pass AfD. Alas, the relevant WP policies appear somewhat inconsistent and their interactions need clarification.
