You derive a simple type by list when you want to define it as a list of values of a specified data type.
The General page of a simple type list property sheet displays the following properties:
| Property | Description |
| ID | ID of the simple type list. Its value must be of type ID and |
|
| unique within the model containing the simple type |
|
| restriction |
| Type | Data type for the list of values |
| Embedded Type | If selected, the type disappears and a simple type is created in |
|
| the schema within the current simple type |
