E.17.1:4.1 - Core role

A conforming viewpoint-bundle library makes three things explicit:

  • which family is being named, via an ordinary family designator interpreted under exact R_L;
  • which U.ViewpointRef members resolve to the exact viewpoint episteme editions packaged by that family;
  • which exact target-kind compatibility condition and catalogue-edition discipline constrain the family.

This lets MultiViewDescribing import a finite viewpoint family from a stable catalogue U.Episteme instead of restating it ad hoc in every local description family.
