Schema validation using multiple schemas

[Adachi Seiichi]

Hi All,

I am trying to validate an xml file using multiple schema files using
Xerces-J 2.5.0.  The xml file specifies the location of schema#1 using
schemaLocation.  Inside of schema#1, schema#2 is specified using
xsd:import.  I get an error when the root element of the xml file is an
element defined in schema#2.

I have used the sample program dom.Counter that comes with Xerces-J
2.5.0, and get the error :
  [Error] test.xml:4:70: cvc-elt.1: Cannot find the declaration of
elment 'ns2:report'.
(I have tried using XML Spy Ver.5 Rel.4 and the DOMCount.exe of Xerces-C 
2.3.0 but
do not get an error.)

Any help will be greatly appreciated.  Here is the sample data I used:

test.xml
--------
<ns2:report xmlns='http://foo.com/namespace1'
   xmlns:ns2='http://foo.com/namespace2'
   xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
   xsi:schemaLocation='http://foo.com/namespace1 ns1.xsd'>
      <textData>sample XML file</textData>
</ns2:report>

ns1.xsd (Schema#1)
------------------
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            targetNamespace="http://foo.com/namespace1"
            xmlns="http://foo.com/namespace1"
            xmlns:ns2="http://foo.com/namespace2"
            elementFormDefault="qualified">

  <xsd:import namespace="http://foo.com/namespace2"
   schemaLocation="ns2.xsd" />

  <xsd:element name="textData" type="xsd:string" 
substitutionGroup="ns2:body"/>

</xsd:schema>

ns2.xsd (Schema#2)
------------------
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            targetNamespace="http://foo.com/namespace2"
            xmlns="http://foo.com/namespace2"
            elementFormDefault="qualified">

  <xsd:element name="report">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element ref="body"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>

  <xsd:element name="body" type="xsd:string"/>

</xsd:schema>

Thanks,

Seiichi
