Check out 14.7 (temp.param). It might be of use to you. 

AFAIK (don't take my word for granted and pl correct me if I I'm
wrong), you could do it like this:

template <class T> class Ref { ... };
template <class T, template <class T> class RefType = Ref> class Collection { ... };

There is an example out there that does stuff like the above. 

None of the compilers I have access to understand this baroque syntax.
