Validating round-trip tests now working for all modules. Ready for next step!
* Added a binding to iso-19139-d_2007_04_17 that fixed an issue that was causing the marshaller to produce invalid XML.
* Added the "xjc:simple" binding to all waterml-related modules. The only exception is gml. I'll need to rewrite its binding from scratch.
* Refactored the pre-test XSLT on tests for all modules. They should be more tolerant of trivial differences.
