Australian English not a supported localization language
When localization is set to en.AU and you try to update the default value of a dictionary entry, the Business Rule "No Duplicates" on sys_documentation throws an error because Australian English is not supported.
Steps to Reproduce
Go to System Localization
Set Default System Language to en.AU.
Note: After changing the value, you might have to log out and then log in again because the session will have cached the set language.
Go to a dictionary entry of Type "String" and set or clear the default value.
The Business Rule "No Duplicates" running on sys_documentation will run and trigger the following error:
A documentation record with the same values of Table, Element and Language fields already exists
Set the localization value to en.GB for UK British Commonwealth English.
