itermset — A set of index terms in the meta-information of a document
               When IndexTerms use the Zone
               attribute to point to index ranges, it may be handy to hoist them
               out of the flow and put them in the document meta-information.
               
            
               The ITermSet element, which occurs in the DocBook containers
               for meta-information, is one place to put them.  ITermSet is
               simply a wrapper around a group of IndexTerms.
               
            
Suppressed.
                  Although more than one ITermSet may appear in the
                  meta-information for a document, neither a relationship nor a specific
                  facility for constructing a relationship is defined.
