It looks like the the templates act as linked documents - you can move them around in the library, and you can rename them, but it is still that template that is used when you publish.
So my question becomes - where is that document linked and can you change that link?
If you can't then the published guidance is NOT clear or accurate. What you would need to do is:
1. Copy the template to create a backup
2. Rename the ORIGINAL
3. Modify the ORIGINAL
If anyone can clarify that'd be fantastic!
I think you're correct. Unless Oracle just forgot to add a Template property to the Assessment / Question objeects, there is no way to tell it to use another template - it will always use "Standard".
Actually, if you go into the source file for the Question (in the Local Repository) then you will find a statement:<QuestionTemplate>0a9ee099-ee19-4bbf-b14b-7efefcc119d4</QuestionTemplate>. You could always manually change this. i wouldn't recommend it, but it does at least show that the functionality is theoreticaly there...
