Here is an overview of the issue:
---------------------------------------------------------------------
        Key: XERCESJ-1010
    Summary: UPA not detected
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Xerces2-J
 Components: 
             XML Schema Structures
   Versions:
             2.6.2

   Assignee: 
   Reporter: George Cristian Bina

    Created: Mon, 20 Sep 2004 8:02 AM
    Updated: Mon, 20 Sep 2004 8:02 AM

Description:
Xerces reports the following document valid:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http://www.example.com/test"
     xmlns="http://www.example.com/test"
     xmlns:xs="http://www.w3.org/2001/XMLSchema">

     <xs:element name="root">
         <xs:complexType>
             <xs:sequence>
                 <xs:element ref="Study" minOccurs="0" 
maxOccurs="unbounded"/>
                 <xs:any namespace="##any" minOccurs="0" 
maxOccurs="unbounded"/>
             </xs:sequence>
         </xs:complexType>
     </xs:element>

     <xs:element name="Study"/>

     <xs:element name="test">
         <xs:complexType>
             <xs:sequence>
                 <xs:any namespace="##other"/>
             </xs:sequence>
         </xs:complexType>
     </xs:element>
</xs:schema>

If the test element is removed or placed before the root element Xerces reports:

SystemID: F:\test\test.xsd
Location: 7:25
Description: E cos-nonambig: "http://www.example.com/test":Study and WC[##any] (or elements
from their substitution group) violate "Unique Particle Attribution". During validation against
this schema, ambiguity would be created for those two particles.
URL: http://www.w3.org/TR/xmlschema-1/#cos-nonambig

The problem seems to be related with ##other because if ##any is 
specified instead the error is reported.

See more details about this issue at http://lists.w3.org/Archives/Public/xmlschema-dev/2004Sep/0050.html
and the other messages in the thread.

Best Regards,
George
