Fxied in CVS.
There is a list of complex types for which we need to check UPA. Somehow the entry for
the "root" type was overwritten by the "test" type, so we were not checking UPA for
the "root" type.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: XERCESJ-1010
Summary: UPA not detected
Type: Bug
Status: Closed
Priority: Major
Resolution: FIXED
Project: Xerces2-J
Components:
XML Schema Structures
Versions:
2.6.2
Assignee: Sandy Gao

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.
