FieldName
By default, the registry key name for a custom field is used as field name, too (=the tagname of the field). Sometimes, it might be desirable to give the registry key a different name than the field itself. Then you can use this parameter to specify the actual field name. The format for the field name can either follow the syntax for database fields (two parts, separated with a slash) or the syntax for BroadcastSystem (two parts, separated with a dot). Arbitrary usage of upper/lower case letters is possible, because the comparison for field names is always case-insensitive.
