   Description:  XSLT stylesheet that is called by the 11_gmd:identificationInfo.xsl and the  15_gmd:metadataMaintenance.xsl stylesheets. It transforms the element in the  element into a value in the MD_MaintenanceFrequencyCode code list, which can be found on page 99 of the ISO standard.

      Initial   Date         Change Request ID   Description
      MMC       07122011                         Insered the MD_MaintenanceFrequencyCodeMetMaint template. This template is similiar to the MD_MaintenanceFrequencyCode
                                                  template, but does not have the gmd:resourceMaintenance and gmd:MD_MaintenanceInformation elements. This is due to                                                     the fact that the gmd:resourceMaintenance element is not in the gmd:resourceMaintenance section.  For the 
                                                  The gmd:MD_MaintenanceInformation element contains only the gmd:MD_MaintenanceFrequencyCode for the 
                                                  identificationInfo section but contains additional elements in the gmd:metadataMaintenance section. 
      MMC        120420113                       Ensured that all the calls to the ISO codelist have the correct URL
