OBJECT IDENTIFIER Type

12-1
The OBJECT IDENTIFIER type is used to contain object identifier values that uniquely identify registered objects.

External Form -- Input and Output

Each sequence of decimal digits punctuated by a period (.), represents a sub-identifier in the series of sub-identifiers that comprise an object identifier value.
