Validation problem using JAXP - Castor 0.9.5.2 or Xerces 2.6.1 bug?

           Summary: Validation problem using JAXP - Castor 0.9.5.2 or Xerces
                    2.6.1 bug?
           Product: Xerces2-J
           Version: 2.6.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: JAXP
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: jpinto@inescporto.pt


I'm using the SourceGenerator from Castor version 0.9.5.2 on the following schema:

<?xml version="1.0" encoding="utf-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://power.inescn.pt/2004/01/compete"
xmlns:compete="http://power.inescn.pt/2004/01/compete"
elementFormDefault="qualified">

<element name="PowerSystem">
  <complexType>
    <sequence>
      <element minOccurs="0" maxOccurs="unbounded" ref="compete:Node"/>
      <element minOccurs="0" maxOccurs="unbounded" ref="compete:Line"/>
    </sequence>
    <attribute name="name" type="string"/>
  </complexType>
  <key name="nodeName">
    <selector xpath="compete:Node"/>
    <field xpath="@ID"/>
  </key>
  <keyref name="fromNodeNameRef" refer="compete:nodeName">
    <selector xpath="compete:Line"/>
    <field xpath="compete:from"/>
  </keyref>
  <keyref name="toNodeNameRef" refer="compete:nodeName">
    <selector xpath="compete:Line"/>
    <field xpath="compete:to"/>
  </keyref>
</element>

<element name="Node" type="compete:NodeType"/>
<complexType name="NodeType">
  <sequence/>
  <attribute name="ID" type="integer"/>
  <attribute name="voltage" type="double"/>
</complexType>

<element name="Line" type="compete:LineType"/>
<complexType name="LineType">
  <sequence>
  <element name="from" type="integer"/>
  <element name="to" type="integer"/>
</sequence>
  <attribute name="ID" type="integer"/>
</complexType>
</schema>

I've set:

org.exolab.castor.parser.validation=true
org.exolab.castor.parser.namespaces=true
org.exolab.castor.marshalling.validation=true

to require validation and set to empty org.exolab.castor.parser and commented
out org.exolab.castor.serializer on the castor.properties file to force using
the default JAXP implementation.

I've updated using the "endorsed" mechanism the Xalan on j2se1.4.2_03 on
Linux/x86 to 2.5.2 and Xerces to 2.6.1 .

I'm getting this stack trace:

org.xml.sax.SAXException: In document:
'file:///home/jpinto/src/eclipse/Test/powersystem.xsd'
Parsing Error : Document is invalid: no grammar found.
Line : 2

If I processe an XML instance of the document that uses this schema using JAXP
and DOM, with validation, I have no problem.

Anybody has an idea?
Do you believe it is an issue on the way Castor sets the parser validation flags
or is it a Xerces problem??

Thank you in advance,

João Luis
