The Developer provides a series of empty master role documents for each supported language. For example, the Roles.en document is the master role document for roles in the English language as determined by the language property of the document. You should not create additional role documents for the same language, as the Developer uses only the first one created for role assignment. For example, if you make a copy of a role document for English and add roles to it, those roles do not appear as assignment choices from any topic Properties toolpane. You should also not move these documents to any other folder in the Library.
You should always use these documents to store roles that can be assigned to topics for role-based filtering in the Player.
