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, command, computeroutput, database, emphasis, entry, filename, 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, term, tertiary, tertiaryie, 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.
