JAXP consists of multiple components. The Xerces and Xalan components 
specifically are by their own and do not have references across the 
boundaries. Our next project is modularization in which Xerces and Xalan 
will definitely be split into difference modules. As for BCEL, since 
it's always by itself, it's preferable to let it that way, unless it 
really affects footprint.
