+
+On deficient compilers not capable of performing the detection,

+ |unspecified-token-seq| \\

+Description
+-----------
+
+Expands into the definition of a boolean n-ary |Metafunction| ``trait``
+such that for any types ``x, a1, a2, ..., an`` ``trait<x, a1, ...,

+value can also be provided at the point of the metafunction
+invocation; see the `Expression semantics` section for details |-- end

+
+
+Parameters
+----------
+
++---------------+-------------------------------+---------------------------------------------------+
+| Parameter | Requirement | Description |
++===============+===============================+===================================================+
+| ``trait`` | A legal identifier token | A name of the metafunction to be generated. |
++---------------+-------------------------------+---------------------------------------------------+
+| ``name`` | A legal identifier token | A name of the member being detected. |
++---------------+-------------------------------+---------------------------------------------------+

++---------------+-------------------------------+---------------------------------------------------+
+| ``default_`` | An boolean constant | A fallback value for the deficient compilers. |
++---------------+-------------------------------+---------------------------------------------------+
+
+
+Expression semantics
+--------------------
+
+For any legal C++ identifiers ``trait`` and ``name``, integral
+constant expression ``n`` greater than or equal to 0, boolean constant
+expression ``c1``, boolean |Integral Constant| ``c2``, and arbitrary
+type ``x``:
+
+.. parsed-literal::
+
+ BOOST_MPL_HAS_XXX_TEMPLATE_NAMED_DEF(trait, name, n, c1)
+
+:Precondition:
+ Appears at namespace scope.
+
+:Return type:
+ None.
+
+:Semantics:
+ Expands into an equivalent of the following class template
+ definition
+
+ .. parsed-literal::
+
+ template<
+ typename X
+ , typename A1, ..., typename An
+ , typename fallback = boost::mpl::bool\_<c1>
+ >
+ struct trait
+ {
+ // |unspecified|
+ // ...
+ };
+
+ where ``trait`` is a boolean |Metafunction| with the following
+ semantics:
+
+ .. parsed-literal::
+
+ typedef trait<x, a1, ..., an>::type r;
+
+ :Return type:
+ |Integral Constant|.
+
+ :Semantics:
+ If |BOOST_MPL_CFG_NO_HAS_XXX_TEMPLATE| is defined, ``r::value
+ == c1``; otherwise, ``r::value == true`` if and only if ``x``
+ is a class type that has a nested type member ``x::template
+ name<a1, ..., an>``.
+
+
+ .. parsed-literal::
+
+ typedef trait< x, a1, ..., an, c2 >::type r;
+
+ :Return type:
