Hi,

     Find attached the schemas and the instance documents.

     I am using MSXML 4.0 parser. The validation goes through successfully
even though there are duplicate keys in
     the instance document.

     Detailed problem description:
     1. I have defined a key for Elem2 which is a global element defined in
GlobalElems.xsd. 
     2. SubMain.xsd included GlobalElems.xsd.
     3. SubMainExtend1.xsd and SubMainExtend2.xsd extend from SubMain.xsd.
     4. MainSchema.xsd is the main schema on which the instance document is
based. This schema imports
         SubMain.xsd and defines an element SubMain which is of SubMainType.
     5. Instance document has two instances of SubMain - SubMainExtend1 and
SubMainExtend2 identified based on
        xsi:type. Duplicate key validation doesn't when SubMain instances
are of different types i.e
        <SubMain xsi:type="submainextend1:SubMainExtend1Type">
        <SubMain xsi:type="submainextend2:SubMainExtend2Type">.

        But the validation happens and a duplicate key found error message
is displayed when SubMain instance is of 
        the same type i.e
        <SubMain xsi:type="submainextend1:SubMainExtend1Type">
        <SubMain xsi:type="submainextend1:SubMainExtend1Type">.

        This problem occurs only when a restriction is applied to the
primary key element.

        What could be the reason???

TIA.
