Revision 197350

1.)  Deprecation of most constructors in XSLTInputHandler in favor of JAXP.
2.)  Removal of unused transformer member variable in XSLTInputHandler.
3.)  Partial modifications -- code from Xalan project -- in order to be
     able to handle command line parameters for XSLT stylesheet.  (Changes
     still needed in XSLTInputHandler.getXMLFilter() -- unsure how to set
     parameters to an XMLFilter.
