> I've observed this behaviour of XML Schemas: When an abstract complexType extends a concrete complexType, the latter is treated as abstract as well. This only occurs when the concrete type is defined in another file that is included into the schema.
> This is reproduced in the following schema files.
> Base.xsd:
>   <?xml version="1.0" encoding="UTF-8"?>
>   <xs:schema targetNamespace="http://w3c.org/test"  
>              xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://w3c.org/test">
>   	<xs:complexType name="Base" abstract="false"/>
>   </xs:schema>
> test.xsd:
>   <?xml version="1.0" encoding="UTF-8"?>
>   <xs:schema targetNamespace="http://w3c.org/test"   
>              xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://w3c.org/test">
>   	<xs:include schemaLocation="Base.xsd"/>
> 	  <xs:complexType name="Derived" abstract="true">
> 		  <xs:complexContent>
> 			  <xs:extension base="Base"/>
>                    </xs:complexContent>
>           </xs:complexType>
> 	  <xs:element name="base" type="Base"/>
>   </xs:schema>
> The validation of the file test.xml below fails with cvc-type.2: The type definition cannot be abstract for element base.
> test.xml:
>   <?xml version="1.0" encoding="UTF-8" standalone="no"?>
>   <base xmlns="http://w3c.org/test" 
>         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
> I'm using the follwing code to validate the schema.
