private Stack createPrefixStack(String prefix){
  Stack fs=new Stack();
  m_namespaces.put(prefix,fs);
  return fs;
}

private Stack createPrefixStack ( String prefix ) { Stack fs = new Stack ( ) ; m_namespaces . put ( prefix , fs ) ; return fs ; }
a more type - safe way of saving stacks under the m_namespaces hashtable .
