This change seems to cross the border between FO tree and area tree. AreaTree had no reference to the fo package (apart from a reference to fo.extensions). AreaTreeHandler extends a class in the fo package and refers to fo/PageSequence. FOInputHandler implements a number of methods of the SAX contenthandler, which is between the fo file and the FO tree. The area package now inherits these methods. AreaTreeHandler throws SAXExceptions. This is a parser based exception type. FOTreeHandler.endPageSequence is the FO tree's activation of a new episode of area tree building. Now the area tree activates itself, based on an event in the FO tree. I believe this change violates the separation between the FO tree and the area tree. I think that separation is a good idea and should be maintained.
