friend declaration for template class

[john smith]

Hi, I have a class like so...

template<class XV, class T> class Foo {
Bar<T>* b;
};

and another class
template<class T> class Bar {
public:
friend template<class XV, class T> class Foo<XV,T>; // wrong
friend class Foo;
// wrong
friend class Foo<XV,T> //
wrong
};

so what is the correct way to give Foo access to Bar's members? Thanks..
