Hi,

I have a problem using group redefinitions and validating both with 
XMLSpy (who complains) and Oxygen (who validates).
My question : who is correct ? Where a I wrong ?

Note: my schema are a lot more complex but I try to make a sample (non 
realistic) in order to isolate my question.

Here is the situation :

base.xsd declares a group called essai :
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns="http://modeles.fr/modeles/reference" 
targetNamespace="http://modeles.fr/modeles/reference" 
elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:element name="ENTER_NAME_OF_ROOT_ELEMENT_HERE">
         <xs:annotation>
             <xs:documentation>Comment describing your root 
element</xs:documentation>
         </xs:annotation>
     </xs:element>
     <xs:group name="essai">
         <xs:choice/>
     </xs:group>
</xs:schema>


other.xsd only includes base.xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns="http://modeles.fr/modeles/reference" 
targetNamespace="http://modeles.fr/modeles/reference" 
elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:include schemaLocation="base.xsd"/>
</xs:schema>


And now, redefine .xsd both redefine base.xsd and includes other.xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns="http://modeles.fr/modeles/reference" 
targetNamespace="http://modeles.fr/modeles/reference" 
elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:redefine schemaLocation="base.xsd">
         <xs:group name="essai">
             <xs:choice>
                 <xs:group ref="essai"/>
                 <xs:element name="test"/>
             </xs:choice>
         </xs:group>
     </xs:redefine>
     <xs:include schemaLocation="other.xsd"/>
</xs:schema>


At this time, XML spy complains but not oxygen 14.2. If I remove the 
include, no problem found.

Any ideas ?

Pierre
