               A Step identifies a unit of action in a Procedure.
               If a finer level of granularity is required for some steps, you
               can embed SubSteps in a Step. Embedded 
               SubSteps contain Steps, so that substeps can
               be nested to any depth.
               
            
The following elements occur in step:
                  abstract, address, anchor, authorblurb, beginpage, bibliolist, blockquote, bridgehead, calloutlist, caution, classsynopsis, cmdsynopsis, constraintdef, constructorsynopsis, destructorsynopsis, epigraph, equation, example, fieldsynopsis, figure, formalpara, funcsynopsis, glosslist, graphic, graphicco, highlights, important, indexterm, informalequation, informalexample, informalfigure, informaltable, itemizedlist, literallayout, mediaobject, mediaobjectco, methodsynopsis, msgset, note, orderedlist, para, procedure, productionset, programlisting, programlistingco, qandaset, remark, screen, screenco, screenshot, segmentedlist, sidebar, simpara, simplelist, stepalternatives, substeps, synopsis, table, task, tip, title, variablelist, warning.
