/**
 * We provide a custom resource factory in order to provider
 * customized XML handling of .nxd and .uidesign files.
 * 
 * We do as much customization as possible via EMF's XMLMap support.
 * This lets us provide names for the <designerData> and <component>
 * elements, and the "id" attributes.
 * 
 * In order to customize property reading and writing we must provide
 * custom XMLLoad, XMLSave, and XMLHandler classes. In the data model properties
 * are stored in a map. Each map entry consists of a key, value pair.
 * EMF's default XML generation is very verbose and includes Java
 * class names in xsi:type attributes. The overriden classes
 * let us provide a much more concise and simple format.
 * 
 * In general the intent is to override only when strictly necessary
 * and let EMF's default handling do as much as possible.
