Yes. Yes, it is.

[C++11: 14.5.1.3/1] A definition for a static data member may be provided in a namespace scope enclosing the definition of the static member’s class template. [ Example:
template<class T> class X {
   static T s;
};

template<class T> T X<T>::s = 0;
—end example ]

Is this the correct way to initialize static data members of template classes?
