Codelists: restricting simpleContent complexTypes

I want to build codelists in a uniform way, and have the authority for the
code list available in the PSVI.  Here's a schema with some commentary:

=======================
<schema targetNamespace="http://xmml.ned.dem.csiro.au/my"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:my="http://xmml.ned.dem.csiro.au/my" elementFormDefault="qualified"
attributeFormDefault="unqualified">
  <!-- ==================================================================
-->

<!--
Start with a simple definition of "CodeType", being a string with a
"codeSpace" attribute, 
and an element of this type
-->

  <complexType name="CodeType">
    <simpleContent>
      <extension base="string">
        <attribute name="codeSpace" type="anyURI" use="optional"/>
      </extension>
    </simpleContent>
  </complexType>
  <!-- ==================================================================
-->
  <element name="name" type="my:CodeType"/>

<!--
Then generate specific codelists by restricting the value of the string to
enumerations, and fix the value of the codeSpace:
-->

  <complexType name="ISOCountry2CharType">
    <simpleContent>
      <restriction base="my:CodeType">
        <enumeration value="AF"/>
        <enumeration value="AL"/>
        <enumeration value="AU"/>
        <enumeration value="ZW"/>
        <attribute name="codeSpace"
fixed="http://www.iso.org/iso/en/prods-services/iso3166ma/02iso-3166-code-li
sts/list-en1-semic.txt" use="optional"/>
      </restriction>
    </simpleContent>
  </complexType>
  <!-- ==================================================================
-->
  <complexType name="ISOCountry3CharType">
    <simpleContent>
      <restriction base="my:CodeType">
        <enumeration value="AFG"/>
        <enumeration value="ALB"/>
        <enumeration value="AUS"/>
        <enumeration value="ZWE"/>
        <attribute name="codeSpace"
fixed="http://unstats.un.org/unsd/methods/m49/m49alpha.htm" use="optional"/>
      </restriction>
    </simpleContent>
  </complexType>
  <!-- ==================================================================
-->
  <complexType name="UNCountryType">
    <simpleContent>
      <restriction base="my:CodeType">
        <enumeration value="Afghanistan"/>
        <enumeration value="Albania"/>
        <enumeration value="Australia"/>
        <enumeration value="Zimbabwe"/>
        <attribute name="codeSpace"
fixed="http://unstats.un.org/unsd/methods/m49/m49alpha.htm" use="optional"/>
      </restriction>
    </simpleContent>
  </complexType>
  <!-- ==================================================================
-->
</schema>
================


Microsoft's online .NET validator
http://www.gotdotnet.com/services/xsdvalidator/Default.aspx says the
attribute restrictions are invalid.  Why?? How can I fix it?


OTOH XML Spy says "ok" but when I give it the one-element document

============
<?xml version="1.0" encoding="UTF-8"?>
<my:name xmlns:my="http://xmml.ned.dem.csiro.au/my"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmml.ned.dem.csiro.au/my
./stringRestriction.xsd">2001 Survey 1</my:name>
============

it complains that 'Value does not match facet enumeration "AF AL AU ZW AFG
ALB AUS ZWE Afghanistan Albania Australia Zimbabwe"'  
Looks like a wierd bug in Spy??
