   * It is highly recommended to do an optimized enumeration by
   * setting the client options
   *   options.flags = Openwsman::FLAG_ENUMERATION_OPTIMIZATION
   *   options.max_elements = 999
   * to get the enumeration result as part of the http request.
   *
   * Otherwise separate pull requests are needed resulting in extra
   * round-trips (client -> wsman -> cimom & back), dramatically
   * affecting performance.
   *
   * call-seq:
   *   client.enumerate(options, filter, uri) -> XmlDoc
