This element is only available if you are using the EBNF Module.
A NonTerminal is a symbol in an EBNF
               Production that represents a portion of the
               grammar.
            
These elements contain nonterminal:
                  action, application, attribution, bibliomisc, bridgehead, citation, citetitle, classsynopsisinfo, code, command, computeroutput, database, emphasis, entry, filename, firstterm, foreignphrase, funcparams, funcsynopsisinfo, function, glosssee, glossseealso, glossterm, hardware, interfacename, keycap, lineannotation, link, literal, literallayout, lotentry, member, msgaud, olink, option, optional, para, parameter, phrase, primary, primaryie, productname, programlisting, property, quote, refdescriptor, refentrytitle, refname, refpurpose, remark, rhs, screen, screeninfo, secondary, secondaryie, see, seealso, seealsoie, seeie, seg, segtitle, simpara, subtitle, synopsis, systemitem, td, term, termdef, tertiary, tertiaryie, th, title, titleabbrev, tocback, tocentry, tocfront, trademark, ulink, userinput.
               
The def attribute
                        contains a URI reference that points to a production where
                        the nonterminal is defined.
                     
Note that this is not
                        an IDREF, it is a URI reference (as, for example, are
                        href attributes on HTML
                        a elements). This is necessary because references to
                        non-terminals might need to cross document boundaries.
