Can someone tell me if this is the best/only way to restrict the values of an attribute?
I only have one attribute named "allow" and I want it to be either YES or NO.

Am I taking a bad approach here? It seems I have one layer to many. How/Can I reduce?

<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" type="allowValues" use="required"/>
</xs:complexType>

<xs:simpleType name="allowValues">
 <xs:restriction base="xs:string">
  <xs:enumeration value="YES"/>
  <xs:enumeration value="NO"/>
 </xs:restriction>
</xs:simpleType>

</xs:schema>
