/**

 * 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.
