+Execution Policy Type Trait
++++++++++++++++++++++++++++
+
+oneDPL provides type trait utilities to detect its execution policy types at compile time for the purpose of
+function overload resolution:
+
+.. code:: cpp
+
+  // Defined in <oneapi/dpl/execution>
+
+  namespace oneapi {
+    namespace dpl {
+
+      template <class T>
+      struct is_execution_policy { /*see below*/ };
+
+      template <class T>
+      inline constexpr bool is_execution_policy_v = oneapi::dpl::is_execution_policy<T>::value;
+
+      namespace execution {
+
+        template <class T>
+        struct is_execution_policy { /*see below*/ };
+
+        template <class T>
+        inline constexpr bool is_execution_policy_v = oneapi::dpl::execution::is_execution_policy<T>::value;
+
+      }
+    }
+  }
+
+``oneapi::dpl::is_execution_policy`` and ``oneapi::dpl::execution::is_execution_policy`` must be treated
+as name aliases to the same class template. It is unspecified, which namespace contains the class template
+definition and its specializations.
+
+.. note::
+   The ``oneapi::dpl::execution::is_execution_policy`` class originated in the oneDPL specification version 1.0,
+   while ``oneapi::dpl::is_execution_policy`` has been added later to better align with the C++ standard.
+   
+   For new code, use of the type trait utilities in ``namespace oneapi::dpl`` is highly recommended. Those
+   in ``namespace oneapi::dpl::execution`` are provided for backward compatibility and may be deprecated in the future.
+
+``is_execution_policy<T>`` must have the characteristics of ``std::true_type`` if ``T`` is one of the above specified or
+implementation-defined oneDPL execution policy types, otherwise it must have the characteristics of ``std::false_type``.
+Following the C++ Standard, ``is_execution_policy<T>`` does not automatically strip references and cv-qualifiers from
+its template argument. [*Note*: Use it with ``std::decay_t<T>`` or similar type transformation utilities. -- *end note*]
