Entity Subtypes

Consider the following rules:

Subtype names must be unique among all entity types, subtypes, and work attribute sets within a model.
Each subtype definition record must include the name of the parent entity or subtype that contains this subtype.
The DSD names must be unique among all DSD names for all entity types and subtypes.
The classifying attribute must be an attribute of the subtype's parent. Subtypes with no classifying attribute will be grouped together in one partitioning.

The following table describes the content of each field type:
