public interface AttributeType
extends PropertyType
```
The type of an attribute.
An attribute is similar to the notion of a UML attribute, or a field of a java object. See the javadoc of Attribute for more info on the semantics of attributes.

Identifiablily
An attribute may be "identifiable". When this is the case the attribute has a unique identifier associated with it. See Attribute#getID(). The type of the attribute specifies wether it is identifiable or not (isIdentified().

  - isIdentified
```
boolean isIdentified()
