      <h:div class="description">By default the reactions in a reactionStepList are assumed to take place in sequence (e.g. one or more products of reaction n are used in reaction n+1 or later. However there are cases where it is known that reactions take place in parallel (e.g. if there is no overlap of molecular identities). Alternatively there are points at which there are two or more competing reactions which may depend on conditions or concentrations. A small semi-controlled vocabulary is suggested.</h:div>
