\r
  This function accepts a <MultiKeywordResp> formatted string, finds the associated\r
  keyword owners, creates a <MultiConfigResp> string from it and forwards it to the\r
  EFI_HII_ROUTING_PROTOCOL.RouteConfig function.\r
\r
  If there is an issue in resolving the contents of the KeywordString, then the\r
  function returns an error and also sets the Progress and ProgressErr with the\r
  appropriate information about where the issue occurred and additional data about\r
  the nature of the issue.\r
\r
  In the case when KeywordString containing multiple keywords, when an EFI_NOT_FOUND\r
  error is generated during processing the second or later keyword element, the system\r
  storage associated with earlier keywords is not modified. All elements of the\r
  KeywordString must successfully pass all tests for format and access prior to making\r
  any modifications to storage.\r
\r
  In the case when EFI_DEVICE_ERROR is returned from the processing of a KeywordString\r
  containing multiple keywords, the state of storage associated with earlier keywords\r
  is undefined.\r

\r
