Guidelines for applying content designators:

The content designators identify the subelements occurring in chronological subdivision headings constructed according to generally accepted thesaurus-building conventions (e.g., Library of Congress Subject Headings, Medical Subject Headings).

A chronological subdivision is used as a subdivision portion of an extended subject or index term access field in bibliographic records.

A chronological term that is used as the lead element of an established heading record is contained in a 150 (Heading - Topical Term) field.

Subfield $w/0 - Special relationship

Code r - Relationship information in subfield $i or $4 [new, 2009]

Subfield $w/1 - Tracing use restriction

Code h - No reference structures [new, 2007]

Subfield $w/2 - Earlier form of heading

Code x - Tracing is not the form of heading established under earlier cataloguing rules [obsolete, 1997] [CAN/MARC only]

Subfield $w/3 - Reference display

Code e - Note only generated from the tracing [obsolete, 1997] [CAN/MARC only]

Code i - Invisible see from reference [obsolete, 1997] [CAN/MARC only]
