# Element instance requirements — the authoritative TOGAF naming rule
#
# core-shapes carries no label shape. arch:Element means "a node in a model", and
# some notations have nodes that are legitimately unnamed (BPMN gateways and
# events, ArchiMate junctions), so naming policy is owned by each metamodel.
# See DD-24 in doc/guide/design-decisions.md.
#
# Targets the 6 abstract architecture-domain roots in each of the two published
# TOGAF namespaces, reaching all 84 element classes through rdfs:subClassOf
# reasoning. TOGAF building blocks are catalogued, governed and reported on by
# name, so every element is required to carry one — TOGAF has no unnamed-by-design
# constructs.
#
# Targets TOGAF classes, never arch:Element. In a merged multi-notation graph,
# targeting arch:Element would impose TOGAF's naming policy on every other
# notation's elements.
