DocBook tags: <literal> versus <firstterm>

  working my way thru the PEAR manual, and i've already noticed a few
examples of the introduction of a new term being tagged as <literal>
rather than <firstterm>.  proposed fix as output of "svn diff":

  <para>
   The smallest unit that can be managed by Pyrus or the PEAR Installer is
-  a <literal>package</literal>.  A package is a collection of files
+  a <firstterm>package</firstterm>.  A package is a collection of files
   that are organized and defined by a meta-information file called
   <link linkend="guide.developers.package2.intro">package.xml</link>.
  </para>


  to be semantically proper, things like that really should be
<firstterm>, should they not?  is there any rendering problem with
using <firstterm> in cases like that?
