Remark 42.50.5. In Situation 42.50.1 it would have been more natural to replace assumption (3) with the assumption: “the chern classes of $E$ are defined”. In fact, combining Lemmas 42.50.2 and 42.50.4 with Lemma 42.35.6 it is easy to extend the definition to this (slightly) more general case. If we ever need this we will do so here.
