>From debugging I observed that although I have set 'fgXercesSchema', for the document element IGXMLScanner::fValidator is of type DTDValidator. When we then process a child element, its is of type SchemaValidator. 

A workaround is to force the parser to use the Schema validator using:
  
  setProperty(XMLUni::fgXercesScannerName, XMLUni::fgSGXMLScanner)

    Summary: Abstract type not handled correctly by cached grammar
       Type: Bug

     Status: Unassigned

             Validating Parser (Schema) (Xerces 1.5 or up only)

Description:
Details:
--------

I have managed to narrow the problem I am having to a simple test case. In the schema, I have an abstract type defined and am using xsi:type with a concrete type in the data file.

If I have a xsi:schemaLocation attribute in my data file, then the test Xml file passes the validation. (I have used DOMCount to verify this)

If I remove xsi:schemaLocation and instead from my source code call loadGrammar() and setFeature(XMLUni::fgXercesUseCachedGrammarInParse, true), I am getting the following error messages:

  Message: Element paramInstance is declared with a type that is
     abstract.  Use xsi:type to specify a non-abstract type

  Message: Attribute 'name' is not declared for   
      element 'paramInstance'

Schema:
-------

<xsd:schema targetNamespace="http://www.temp.org" xmlns:tmp="http://www.temp.org" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <!-- 
      Define a 'paramInstance' element
      NOTE: We use an abstract base to allow for extension
      -->
   <xsd:complexType name="ParamInstanceType" abstract="true" />
   <xsd:element name="paramInstance" type="ParamInstanceType" />
   <!-- 
      Specifying a concrete type
     -->
   <xsd:complexType name="ConcreteParamInstance">
      <xsd:complexContent>
         <xsd:extension base="tmp:ParamInstanceType">
            <xsd:attribute name="name" type="xsd:string" use="required" />
         </xsd:extension>
      </xsd:complexContent>
   </xsd:complexType>
</xsd:schema>

Test data file:
---------------
<paramInstance xmlns="http://www.temp.org"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:type="ConcreteParamInstance" name="param1" />
