Facet indicator

notational device that indicates the start of a new facet within a synthesized compound classmark

Examples of facet indicators are the 0 in the Dewey Decimal Classification, and parentheses and quotation symbols in the Universal Decimal Classification. In the past the term facet indicator has been used as synonymous with node label but that usage should be avoided, to avoid confusion.
