New interface XMLizable (copied from Apache Excalibur) to mark classes that can serialize themselves to XML (SAX stream).

New interface ContentHandlerFactory (plus associated Factory with Service discovery) for sub-document parsing plug-ins. Used by the area tree but could be used independently.
ExtensionAttachments are now part of the area tree and are written by XMLRenderer and parsed by AreaTreeParser.
The PS Extensions are extended to support serialization to and deserialization from XML.
Added a test case that tests the PS Extension WRT the handling in the area tree XML.

+  <info>
+    <p>
+      This test checks the PostScript extension for custom setup code. The extension attachments need to show
+      up in the area tree XML so the AreaTreeParser can fully restore the area tree.
