Re: Validating Schemas With Xerces

That didn't help, the schema file was the following one

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ns="urn:mynamespace"  targetNamespace="urn:mynamespace"
elementFormDefault="qualified" >
<xsd:element name="switch">
           <xsd:complexType>
                        <xsd:sequence>
                                    <xsd:element name="value" minOccurs="2"
maxOccurs="2">
                                               <xsd:simpleType>
                                                           <xsd:restriction
base="xsd:string">

<xsd:enumeration value="on" />

<xsd:enumeration value="off" />
                                                           </xsd:restriction>
                                               </xsd:simpleType>
                                    </xsd:element>
                        </xsd:sequence>
            </xsd:complexType>
            <xsd:unique name="uni">
                        <xsd:selector xpath="ns:switch" />
                        <xsd:field xpath="ns:value" />
            </xsd:unique>
</xsd:element>
</xsd:schema>

I received a private email that mentioned that Xerces 1.4.4 has difficulty
validating schemas and I should try 2.0.0B4

No matter how well it would perform, I will never construct any sort of

virtually inaccessible vulnerable spot.
