Unfortunately the files.zip attachment only contains the binding.xml and build.xml file, without any of the classes used by the binding. In order to be sure the problem is fixed I need to have the class files, too.

I've changed the NameAttribute.equals() method to use safe comparisons, so that the NPE should no longer occur. I don't know if this was masking a deeper problem, though.

Considering this fixed unless I hear otherwise (hopefully with corrected demonstration code).
