# ShEx compact syntax — generated from the same shape model as the
# SHACL and ShExJ artifacts beside this file (BHE-DES-RDF-001 §10.5).
#
# Two differences from the SHACL are inherent to ShEx, not omissions:
#   * Targeting lives in a ShapeMap, outside the schema. A shape whose
#     SHACL form uses sh:targetClass carries an `a [schema:X]` triple
#     constraint instead; sh:targetSubjectsOf has no equivalent and is
#     recorded in the comment above the shape.
#   * Severity has no ShEx equivalent and is carried as an annotation.
