Description

Setting a property on a static data object with an object of a type extended in a dynamic model results in a ClassCastException.

Scenario:
Static schema-
<xsd:complexType name="CustomerType">
<xsd:all>
<xsd:element name="number" type="xsd:integer" />
<xsd:element form="unqualified" name="info" type="InfoType" />
</xsd:all>
</xsd:complexType>

<xsd:complexType name="InfoType" abstract="true"/>

Dynamic Schema
<xsd:complexType name="InfoType">
<xsd:complexContent>
<xsd:extension base="staticNS:InfoType">
<xsd:sequence>
<xsd:element name="zipcode" type="xsd:string" />
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>

The following will fail:
DataFactory factory = scope.getDataFactory();
factory.create(CustomerType.class).setDataObject("info", factory.create("dynamicNS", "InfoType"));

It should be legal to assign a property to an object if they are in the same hierachy.

Steps to reproduce within Tuscany:
Testcase org.apache.tuscany.sdo.test.ExtensibleTestCase will break if 'InfoType' defined in extensible/customer.xsd is marked as abstract.
