Sorry!
It does support template template parameters. All that is needed is
wrap the template template parameter in a type:

struct tag {};
template <template<typename> class T>
class wrap
{
  template <typename ApplyT>
  struct apply
  {
    typedef T<ApplyT> type;
  };
};

template <template<typename> class T>
struct a0_is : parameter::template_keyword<tag, wrap<T> >
{};

And just use the tag again in the parameter:parameters.

It would be a very addition to a "tips section" in the documentation.
