E.17.1:14.2 - Local overlays vs new bundles
A local project often wants a small adaptation: one extra concern note, one narrower stakeholder emphasis, one local naming convention. E.17.1 prefers explicit overlays or new editions over silent mutation.
A practical rule is:
- if the local project selects a subset or adds only didactic/publication material, keep exact catalogue edition L and its declaration unchanged and declare the local subset or annex; do not treat the overlay as declaration content;
- if the local project changes viewpoint membership or meaning, publish a new local catalogue edition carrying the revised or new family declaration.
This is how bundle reuse remains trustworthy across organizations.
