is it possible in a schema

Apologies for my lack of schema knowledge!!

I have a list of 5 elements. I want to have at least 2 of them appearing.
With none of them appearing twice.

Is there a cleann way of defining this other than defining a choice between 
each possible combination!!

Any help would be much appreciated
