+
+    \brief Asserts that the sequence is a Boost PP array.
+
+    The macro checks that the sequence is a Boost PP array.
+    If it is not a Boost PP array, it forces a compiler error.
+    
+    The macro normally checks for a Boost PP array 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.
+
+    sequence = a possible Boost PP  array.
+
+    returns  = Normally the macro returns nothing. 
+    
+               If the sequence is a Boost PP array, nothing is 
+               output.
+              
+               For VC++, because there is no sure way of forcing  
+               a compiler error from within a macro without producing
+               output, if the sequence is not a Boost PP array the 
+               macro forces a compiler error by outputting invalid C++.
