Different values can be defined for the property Variety:

Variety: type / restriction

    Defines an attribute by referencing an existing simple type using the Datatype property.

    Available if the simple type is a predefined type.

    Defines an attribute by restricting an existing simple type which is referenced by the Datatype property. This property is then mapped to the Base type attribute.

    Available if the simple type is a predefined type.

    Only available if the simple type is a user-defined type.

Icon in schema tree Element unknown

Adds an element declaration that references an existing type. This schema tree item is usually chosen if a user-defined type is referenced and the type is not known to the Schema Editor. Thus, the Schema Editor cannot determine whether the element is an element simple, element complex or element with attributes. If the declaration of the type is loaded into the Schema Editor, the tree item is updated.
