All AIXM list of values are open <<codelist>>. In addition to the predefined values (such as MON, TUE, WED, etc. for CodeDayType), it is possible to also use ‘OTHER:’ followed by a custom code. For example, the value ‘OTHER:3RD_MON’ could be used in a Timesheet to indicate ‘the third Monday of each month’.
Permission
The Data Set may contain attributes that use the embedded codelist extension mechanism (‘OTHER:’ followed by a custom code), with exception of those attributes where the use of the ‘OTHER:...’ values is explicitly forbidden through the data coding rules.
