This example of an established heading for a meeting name shows occasions when a subfield code is input before a mark of punctuation. Generally content designators follow commas, periods, colons, etc. In both the 111 and the second and third 670 fields, the content designators precede the opening parenthesis.
The 4XX field includes a control subfield $w that produces a special display and indicates any reference structure restrictions. In this case, the subfield $w codes identify the form of name in the 4XX as the pre-AACR 2 form of heading established under earlier cataloging rules and suppress the display of a cross reference.
