Designator of the Edition
The edition number as an unadorned numeric or alphabetic value.
When an edition statement contains ordinals (such as “3rd”) or words such as “3rd print edition”, this attribute can preserve the edition number as a simple, machine-processable number, such as “3”.
|The numeral or alphabetic character that indicates the edition number||The straight unadorned edition number, for machine processing. Typically this is a number such as “4” or an alphabetic character such as “A”.|
|Restriction||@designator is an optional attribute; there is no default.|
