Provide a list of default licences for the document Rights attribute.
Usually users don't know what to do with the "Rights" attribute of CPS documents, so we could provide a vocabulary of existing Free/Libre/OpenSource software licences so that the user can choose between for example the GNU GPL licences, the Creative Commons licences, etc.
Multiple selection should be possible since multi-licencing is possible.
The Manager can add/remove licences to the licences' vocabulary.
This would make possible for an organization to monitor very effectively under what terms its documents and files to download are distributed.
