If JDOM supported a QName type of object, and allowed

	Element.getChildren(QName qname)

this would be a lot simpler:

public interface MyDocumenType
    public final static Namespace MY_DOC_NS = new Namespace(..)
    public final static QName DEVELOPER_NAME = new QName( "developer", MY_DOC_NS );

Then, in your application you could just do:

	element.getChildren( MyDocumentType.DEVELOPER_NAME )

Alas, we don't have a QName object...
