Fixed a memory-leak: The FO tree part of a page-sequence was not released when a page-sequence was finished.
Added a "MemoryEater" debug helper which can replicate page-sequences of a regular FO file using the fo-replicator.xsl. Without the fix a JVM set to the normal 64MB heap size throws an OutOfMemoryError when replicating readme.fo 150 times. With the fix the memory consumption doesn't go above 10MB for the 1350 pages. Note that about one third of the time goes into garbage collection.

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.
