      Preserved from prior description (commit 6e634651):

      A generic identifier consisting of a scheme and value pair.
      **Purpose**:
      Base identifier class for any entity (not just heritage custodians).
      Used when a simple scheme + value identifier is needed.
      **For heritage custodian identifiers**: Use `CustodianIdentifier` which
      extends this class with provenance tracking (allocation agency, standard, etc.)
      **Schema.org Alignment**:
      Maps to schema:PropertyValue which represents a property-value pair.
      - propertyID → identifier_scheme
      - value → identifier_value
    broad_mappings:
    - schema:PropertyValue

    class_uri: crm:E42_Identifier
    description: >-
      Identifier assigned to a heritage custodian with allocation provenance,
      issuing context, and governance traceability.
