Re: derived types in instance documents

[George Cristian Bina]

Hi,
Make sure you are using Xerces 2.6.2. I cannot reproduce your error with 
the following documents. The instance is reported valid by Xerces 2.6.2 
against the schema.

test.xml
<?xml version="1.0" encoding="UTF-8"?>
<ns1:UserNameToken xmlns:ns1="wsse"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="wsse test.xsd">
    <ns1:Username xsi:type="ns1:EncodedString"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
       EncodingType="someType">test</ns1:Username>
</ns1:UserNameToken>
test.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
targetNamespace="wsse"
    xmlns:wsse="wsse" xmlns:wsu="wsu" elementFormDefault="qualified">
    <xsd:import namespace="wsu" schemaLocation="wsu.xsd"/>
    <xsd:complexType name="AttributedString">
        <xsd:simpleContent>
            <xsd:extension base="xsd:string">
                <xsd:attribute ref="wsu:Id"/>
                <xsd:anyAttribute namespace="##other" 
processContents="lax"/>
            </xsd:extension>
        </xsd:simpleContent>
    </xsd:complexType>
    <xsd:complexType name="EncodedString">
        <xsd:simpleContent>
            <xsd:extension base="wsse:AttributedString">
                <xsd:attribute name="EncodingType" type="xsd:anyURI"/>
            </xsd:extension>
        </xsd:simpleContent>
    </xsd:complexType>
    <xsd:complexType name="UsernameTokenType">
        <xsd:sequence>
            <xsd:element name="Username" type="wsse:AttributedString"/>
            <xsd:any processContents="lax" minOccurs="0" 
maxOccurs="unbounded"/>
        </xsd:sequence>
        <xsd:attribute ref="wsu:Id"/>
        <xsd:anyAttribute namespace="##other" processContents="lax"/>
    </xsd:complexType>
    <xsd:element name="UserNameToken" type="wsse:UsernameTokenType"/>
</xsd:schema>

wsu.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
targetNamespace="wsu" attributeFormDefault="qualified">
    <xs:element name="test"/>
    <xs:attribute name="Id" type="xs:string"/>
</xs:schema>

Best Regards,

All,
 
I have the following types defined in a schema:
 
 <xsd:complexType name="AttributedString">
  <xsd:simpleContent>
   <xsd:extension base="xsd:string">
    <xsd:attribute ref="wsu:Id"/>
    <xsd:anyAttribute namespace="##other" processContents="lax"/>
   </xsd:extension>
  </xsd:simpleContent>
 </xsd:complexType>

 <xsd:complexType name="EncodedString">
  <xsd:simpleContent>
   <xsd:extension base="wsse:AttributedString">
    <xsd:attribute name="EncodingType" type="xsd:anyURI"/>
   </xsd:extension>
  </xsd:simpleContent>
 </xsd:complexType>
 <xsd:complexType name="UsernameTokenType">
  <xsd:sequence>
   <xsd:element name="Username" type="wsse:AttributedString"/>
   <xsd:any processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
  </xsd:sequence>
  <xsd:attribute ref="wsu:Id"/>
  <xsd:anyAttribute namespace="##other" processContents="lax"/>
 </xsd:complexType>
Note that EncodedString is derived from AttributedString.
 
The following passes XML Validation:
 
 <ns1:UsernameToken>
  <ns1:Username xsi:type="ns1:AttributedString" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> 
<http://www.w3.org/2001/XMLSchema-instance";>>
my username</ns1:Username>
 </ns1:UsernameToken>
And so does this:
 
 <ns1:UsernameToken>
  <ns1:Username>my username</ns1:Username>
 </ns1:UsernameToken>
 
But Xerces throws an error on the following:
 
 <ns1:UsernameToken>
  <ns1:Username EncodingType="someType" xsi:type="ns1:EncodedString" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>my 
<http://www.w3.org/2001/XMLSchema-instance";>my> username</ns1:Username>
 </ns1:UsernameToken>
Xerces says:
 
cvc-elt.4.3: Type 'ns1:EncodedString' is not validly derived from the 
type definition, 'AttributedString', of element 'ns1:Username'.
 
It's not clear to me what is wrong with the XML.  Can someone shed some 
light? 
 
Thanks.
