Remove identifier field filtering
Remove identifier field filtering

Fields declared as identifier were skipped when binding the state of the
Java object to the RDF model. Often, however, this identifier is a
natural source, for instance a name attribute which should become a
property in the model. Hence, I have removed the condition where
identifier fields are skipped.
