Change it to:
company.xy.             SOA     dns.company.xy. hostmaster.company.xy. (
                                1998092900      ; Serial number
                                     86400      ; Refresh     1 day
                                      7200      ; Retry       2 hours
                                   3600000      ; Expire      41.67 days
                                    172800     ; Minimum TTL 2 days
                          )
and it's perfectly valid again, but with the closing bracket
not seemingly being part of the MinTTL field.
