NAME
Reserved_Data_Types - Built-in reserved Data Types.
DESCRIPTION
The data type names described in the table below are reserved and cannot be used by
applications as user-defined type names. The vector data type names defined in
vectorDataTypes(3clc), but where n is any value other than 2, 3, 4, 8 and 16, are also
reserved.
