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

Key: XERCESC-1263
Summary: Abstract type not handled correctly by cached grammar
Type: Bug
Status: Unassigned
Priority: Major
Project: Xerces-C++
Components:
Validating Parser (Schema) (Xerces 1.5 or up only)
Versions:

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: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" />
