"fixed" attribute on enumeration facet

Since the enumeration facet is defined as follows:

  <xs:element name="enumeration" id="enumeration" type="xs:facet">
    <xs:annotation>
      <xs:documentation
        source="http://www.w3.org/TR/xmlschema-2/#element-enumeration"/>
    </xs:annotation>
  </xs:element>

and xs:facet is defined as:

  <xs:complexType name="facet">
    <xs:complexContent>
      <xs:extension base="xs:annotated">
        <xs:attribute name="value" use="required"/>
        <xs:attribute name="fixed" type="xs:boolean" use="optional"/>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

I am wondering what the meaning of the "fixed" attribute is within an
"enumeration" element.  E.g.:

<enumeration value="72" fixed="???" />

Regards,

Ian.
