I do it this way as well, but as an aside, you don't need the getters and setters.  JiBX can access 
the fields directly.

You can add whatever you want in here, but the downside is that it has to be set by applicaiton logic.

public class IsisExchangeDoc
	implements edu.iris.dmc.app.JibxVersionedObject
{
	// XXX For JibX. YUK.
	private String _schemaNS = "http://www.w3.org/2001/XMLSchema-instance";
	private String _schemaFile = "file:/users/linus/workspace/isis/xml/isis.xsd";

	private String bindingVersion = null;
[...]
}

	<mapping class="edu.iris.dmc.isis.IsisExchangeDoc" name="IXDoc">
		<value field="_schemaNS"
			name="xmlns:xsi"
			style="attribute"
			usage="optional" />
		<!--default="http://www.w3.org/2001/XMLSchema-instance" /-->
		<!-- defaults are not really necessary since I don't care about setting them
			when unmarshalling. -->
		<value field="_schemaFile"
			name="xsi:noNamespaceSchemaLocation"
			style="attribute"
			usage="optional" />
		<!--default="file:/users/linus/workspace/isis/xml/isis.xsd"/-->
		<value field="bindingVersion" name="bindingVersion" style="attribute"
  			default="IXD"/>
[...]
	</mapping>
