Vic and others: We need JDK 1.7 in order to compile this class, the current build.xml file specifies source=1.5 and this restricts the switch statement in the class. It used to have very complicated if-then-else statements and I changed them for a switch-case in order to enhance the navigation of the XML nodes in the UTD documents. I guess we should remove this source command in build.xml or specify source="1.7" as this is the current JDK release. François.
