  This abuses the S3 object system to get the job done.  
  Typically this is first called with an object of class
  \code{XMLNode}.  The \code{getParameterName.XMLNode} method changes
  the class of its argument to be the name of the tag for the
  \code{XMLNode}.  It then recalls the generic function and the
  appropriate method is called.
