----------------------------------------

             Summary: Error not reported on duplicate attributes
                 Key: XERCESJ-1615
                 URL: https://issues.apache.org/jira/browse/XERCESJ-1615
             Project: Xerces2-J
          Issue Type: Bug
          Components: XML Schema 1.0 Structures, XML Schema 1.1 Structures
    Affects Versions: 2.11.0
            Reporter: Octavian Nadolu


If I validate the following schema Xerces does not complain about the the duplicate attribute. The same attribute group is referred twice.

You can reproduce the issue on the xml-schema-1.1-dev branch.

-------- schema.xsd --------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:complexType name="baseType">
        <xs:attributeGroup ref="globalAttributes"/>
        <xs:attributeGroup ref="globalAttributes"/>
    </xs:complexType>
    
    <xs:attributeGroup name="globalAttributes">
        <xs:attribute name="id" type="xs:ID"/>
    </xs:attributeGroup>
</xs:schema>
