Re: Using xsd:type in xml files

Hi Nicolas,

Here it is an example, it may help. From the error message it seems that 
you are using the wrong namespace for the type attribute.

test.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
     <xs:element name="foo" type="foo"/>
     <xs:complexType name="foo">
         <xs:sequence>
             <xs:element ref="bar" maxOccurs="unbounded"/>
         </xs:sequence>
     </xs:complexType>
     <xs:element name="bar" type="bar"/>
     <xs:complexType name="bar"/>
     <xs:complexType name="bar1">
         <xs:complexContent>
             <xs:extension base="bar">
                 <xs:choice>
                     <xs:element name="bar1Content"/>
                 </xs:choice>
             </xs:extension>
         </xs:complexContent>
     </xs:complexType>
     <xs:complexType name="bar2">
         <xs:complexContent>
             <xs:extension base="bar">
                 <xs:choice>
                     <xs:element name="bar2Content"/>
                 </xs:choice>
             </xs:extension>
         </xs:complexContent>
     </xs:complexType>
</xs:schema>

valid instance:

<foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="test.xsd">
     <bar xsi:type="bar1">
         <bar1Content></bar1Content>
     </bar>
     <bar xsi:type="bar2">
         <bar2Content></bar2Content>
     </bar>
     <bar/>
</foo>

George
