This is a typical case of forward declaration, where the names do not
matter, only the arity (for types) and actual types (for non-types) does.

    namespace std { template <typename, typename, typename, typename> class
map; }

It occurs even more frequently in friends declaration, in my experience.

In essence, the idea is similar to not naming the unused parameters of a
function.
