issues with permission element in vdb-deployer.xsd contains problematic choice node

Having a lot of trouble trying to tweak our JaxB VDB element classes to accommodate the permission's choice node which contains a <sequence> and an <element>.

This structure is basically impossible to unmarshall using JAXB annotations (i.e. @XmlElements(value= {}) )

Would clean things up to convert the <allow-language> element to an attribute: <xs:attribute name="allow-language" type="xs:boolean"/> and place it on the <permission> element AND remove the <choice> node entirely
