Using IDREF and enumeration within Union

[stran]

I'm trying to create a simple type that holds two different types. The first is IDREF and the second is an enumeration of string. When I generate a sample xml, I can enter any ID previously stated in the xml and validates correctly. When I try to use one of the enumeration in the drop down list, the xml will not validate.
When I validate the xml in xmlspy, i get the error message "IDREF 'endofprogam': referenced ID 'endofprogam' was not found."
Anyone knows a solution to having a union of enumeration and IDREF? I would appreciate any help.

<xs:simpleType name="Persist_Enum_Type">
<xs:annotation>
<xs:documentation>Persist gives the UTR multiple options of lifetime</xs:documentation>
</xs:annotation>
<xs:union memberTypes="xs:IDREF">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:annotation>
<xs:documentation>
End of Program (EOP)
End of Children (EOC)
End of Lifetime (EOL)
Persist to Label (PTL)
</xs:documentation>
</xs:annotation>
<xs:enumeration value="endofprogram"/>
<xs:enumeration value="endofchildren"/>
<xs:enumeration value="endoflifetime"/>
<xs:enumeration value="persisttolabel"/>
</xs:restriction>
</xs:simpleType>
</xs:union>
</xs:simpleType>

Hopefully you're still looking for this...

I sounds like MSXML.NET validates XML a bit better than XMLSpy. I am not sure how accurate this is, but I say give it a whirl. It was suggested that a good way to write it would be:

<union>
<simpleType of enumeration>
<simpleType of IDREF>
</union>
 

Hope this helps!
