Sound doctrines

Idea

A class Φ\Phi of diagram shapes for limits — or more generally a class of weights for limits — is called sound as a doctrine of limits [Adámek, Borceux, Lack & Rosicky (2002)] if it behaves nicely when paired with the class Φ +\Phi^+ of all colimit shapes (or weights) that commute with Φ\Phi-limits in Set (or more generally in the base of enrichment).
