                  <li><b>Terms & Properties</b>: Gives definitions, synonyms,
                    abbreviations, codes, and other information.</li>

                    directly related to this concept as parents, children,

                    adds inverse relationships not asserted bidirectionally
                    in the source data file; this is often useful for 
                    navigational purposes, but might be confusing, and 
                    will be evaluated for adjustments in future releases.</li>
                  <li><b>Synonym Details</b>: For each term or abbreviation,
                    shows its term type, source, and code (for sources
                    that have them).</li>
