RE: is the best/only way to restrict the values of an attribute

I'm not sure if this is that much better, it does save a line or two. 


<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="TEIMSettings">
 <xs:complexType>
  <xs:sequence>
    <xs:element name="LACAllowTIRUpload" type="allowAttribute"/>
    <xs:element name="LACAllowTIRDelete" type="allowAttribute"/>
  </xs:sequence>
 </xs:complexType>
</xs:element>

 <xs:complexType name="allowAttribute" >
  <xs:attribute name="allow" use="required"> 
   <xs:simpleType>
    <xs:restriction base="xs:string">
     <xs:enumeration value="YES"/>
     <xs:enumeration value="NO"/>
    </xs:restriction>
   </xs:simpleType>
  </xs:attribute>
 </xs:complexType>

</xs:schema>

Actually I'm wrong. Although it has fewer constructs it is longer. Go
figure.
