<p>The macro checks that the sequence is a VMD type. If it is not a VMD type, it forces a compiler error.</p>
<p>The macro normally checks for a VMD type only in debug mode. However an end-user can force the macro to check or not check by defining the macro BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.</p>
<p>d = The next available BOOST_PP_WHILE iteration. sequence = a possible VMD type.</p>
