+Not every smart pointer is compatible with [*Boost.Intrusive]:
 
-*  It must support the same operations as a raw pointer, except casting.
-*  It must be convertible to a raw pointer and constructible from a raw pointer.
-*  It must have the same ownership semantics as a raw pointer. This means that
-   resource management smart pointers (like `boost::shared_ptr`) can't be used.
+   * It must be compatible with C++11 [@http://en.cppreference.com/w/cpp/memory/pointer_traits `std::pointer_traits`]
+      requirements. [*Boost.Intrusive] uses its own [classref boost::intrusive::pointer_traits pointer_traits]
+      class to implement those features in both C++11 and C++03 compilers.
+   * It must  have the same ownership semantics as a raw pointer. This means that
+      resource management smart pointers (like `boost::shared_ptr`) can't be used.
 
 The conversion from the smart pointer to a raw pointer will be implemented as a recursive call to
 `operator->()` until the function returns a raw pointer.
