Every file attribute list is identified by its name field in the .xml
                                          file. This name is a unique internal name that does not display on the
                                          administrator console.
If the file contains a customized file attribute list that already
                                          exists, Cloud Email Gateway
                                             Protection overwrites the
                                          existing file attribute list. If the file contains any predefined file
                                          attribute list, Cloud Email Gateway
                                             Protection skips the
                                          predefined file attribute list while importing the remaining customized
                                          file attribute lists.
