handling of multiple CREATOR / PUBLISHER... ACDD values
It is now possible to enter multiple names (comma delimited list) as CREATOR_xxx . The default values should also be handled appropriately. For example, when providing ACDD_CREATOR = C. Fierz, M. Bavay
, then ACDD_CREATOR_INSTITUTION
should not default to the domain name of the computer but to 2 domain names, comma-delimited so the ACDD fields are consistent (otherwise the user receives an error message regarding an ACDD field he did not even provide!).
