A definition for a static data member or static data member template may be
provided in a namespace scope enclosing the definition of the static member's
class template[.](#1.sentence-1)

[*Example [1](#example-1)*: template<class T> class X {static T s;};template<class T> T X<T>::s = 0;

struct limits {template<class T>static const T min; // declaration};

template<class T>const T limits::min = { }; // definition — *end example*]

An explicit specialization of a static data member declared as an array of unknown
bound can have a different bound from its definition, if any[.](#2.sentence-1)

[*Example [2](#example-2)*: template <class T> struct A {static int i[];};template <class T> int A<T>::i[4]; // 4 elementstemplate <> int A<int>::i[] = { 1 }; // OK, 1 element — *end example*]
