                    <h:tt>moleculeList</h:tt> can contain several molecules. 
                    These may be related in many ways and there is are controlled
                    semantics. However it should not be used for a molecule
                    consisting of descendant molecules for which molecule
                    should be used.
          A moleculeList can contain nested moleculeLists.

The <h:tt>molecule</h:tt>s can be a set of reference molecules which occur in the <h:tt>molecule</h:tt>s and can be referenced. This makes the molecules more readable and normalizes data when molecules are used more than once.</h:div>
