+<!--  This xsd is in part a workaround for the fact that JAXB (and the Eclipse
+	  schema editor) don't let you import the same namespace more than
+	  once.
+	  
+	  This technique suggested by lukas, at http://alweb.homeip.net/dw0rm/dblog/?p=72
+	  
+	  Its a good approach, since it allows us to proceed with minimal
+	  alteration to the original XSD's.
