  <para>The {@}id} inline tag is used only in tutorials/extended documentation.  It is very simply designed to solve the problem of identifying sections for hyperlinking.  For instance, in the DocBook Converter, id's are in the format package.packagename[.subpackagename].file[.sectionname], where file is either the classname, function/method name, or summary.  In the other Converters, the id is not nearly as restrictive, but this inline tag allows for the potential of future converters that are equally exacting.  Use <![CDATA[<refsect1 id="{@}id idname}">]]> in the tutorial (tutorialname.pkg/tutorialname.cls/tutorialname.proc) to do this.</para>
 <para>The {@}id} tag is context-sensitive, and will pre-pend the id of the current refsect1, refsect2, or refsect3 to any {@}id}, allowing further error control.</para>
 <caution>The sectionname may only consist of <emphasis>lower-case</emphasis> letters, numbers, and hyphens "-."  No other characters are allowed</caution>
