To create a complex type from a restricted string and adding an attribute,
you should:
<!-- create the restricted string type -->
<xs:simpleType name="LimString">
<xs:restriction base="xs:string">
<xs:minLength="1"/>
...
</xs:simpleType>
<!-- create the complex type -->
<xs:complexType name="EnumValue">
<xs:simpleContent>
<xs:extension base="LimString"> <!-- Note: extension
!-->
<xs:attribute name="restricted" type="xs:boolean" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
