 void processingInstruction(java.lang.String target, java.lang.String data)
          Handle the xml-stylesheet processing instruction.
 void setBaseId(java.lang.String baseId)
          Added additional getter and setter methods for the Base Id to fix bugzilla bug 24187
 void setURIResolver(URIResolver resolver)
          Get the object that will be used to resolve URIs in href in xml-stylesheet processing instruction.
