+/** \def BOOST_VMD_IS_TYPE(sequence)
+
+    \brief Tests whether a sequence is a VMD type.
+
+    sequence = a possible VMD type
+    
+    returns = 1 if the sequence is a VMD type, 
+              0 if it is not.
+    
+    If the sequence is not a VMD data type this macro could lead to
+    a preprocessor error. This is because the macro
+    uses preprocessor concatenation to determine if the sequence
+    is an identifier once it is determined that the sequence does not
+    start with parentheses. If the data being concatenated would
+    lead to an invalid preprocessor token the compiler can issue
+    a preprocessor error.
