Successive restriction of enumerated content in complex types

Message-ID: <002b01c2f2ee$5dd91040$78941bac@hyperion.com>
To: <xmlschema-dev@w3.org>

In my xbrli namespace I have the following type:

 <complexType name="stringItemType">
  <simpleContent>
   <extension base="string">
    <attribute name="nonNumericContext" type="IDREF" use="required"/>
    <anyAttribute namespace="##other" processContents="lax"/>
   </extension>
  </simpleContent>
 </complexType>

I now define a new type in my dt namespace as follows:

 <complexType name="accountTypeItemType">
  <simpleContent>
   <restriction base="xbrli:stringItemType">
    <enumeration value="account"/>
    <enumeration value="bank"/>
    <enumeration value="employee"/>
    <enumeration value="customer"/>
    <enumeration value="job"/>
    <enumeration value="vendor"/>
    <enumeration value="fixed-asset"/>
   </restriction>
  </simpleContent>
 </complexType>

I now try to further restrict it in another namespace thus:

 <complexType name="moreRestrictedAccountTypeItemType">
  <simpleContent>
   <restriction base="dt:accountTypeItemType">
    <enumeration value="account"/>
    <enumeration value="bank"/>
    <enumeration value="employee"/>
   </restriction>
  </simpleContent>
 </complexType>

XML-Spy chokes on this by highlighting

base="dt:accountTypeItemType"

and giving the error message "simpleContent cannot have a base that is a
complexType with complexContent" which makes no sense to me because
accountTypeItemType does not have complexContent.

A JAXP 1.2/Xerces 2 validator says this is valid XML Schema

Is it?

Thanks

Hugh
