JUnit Test cases to test URI resolution using custom URIResolvers. They are not yet integrated into the test suite as the second test fails and the first test needs some changes in the code (see TODO).
1. Implemented validateChildNode() for fo:simple-page-master. This may cause some stress with the user community--as any declared fo:region-xxxx children must follow a specific ordering.
2. Modified several of our sample and test FO files to be compliant with the XSL spec with respect to the change above.
3. @todo's added to FO's still missing validateChildNode()
4. New FONode missingPropertyError() method created, for the major cases where missing properties should halt processing.
5. Various cleanup in our layout-master-set and region classes, including the removal of error checks that are no longer needed due to validateChildNode() being implemented.
