* Differences between XML output and the "current.xml" file:
* - classes in same package are not all grouped together; nothing is sorted
* - no "deprecated" on fields and methods
- * - no "value" on fields
* - no parameter names
* - no generic signatures on parameters, e.g. type="java.lang.Class<?>"
* - class shows declared fields and methods; does not show inherited fields
