mal_inline_em = element em {

</code></synopsis>

<p>Use the <code>em</code> element to emphasize text.  You may use <code>em</code>
to stress certain words in a sentence.  Do not use <code>em</code> to effect a
particular typographic style, since it may be rendered differently by different
display tools.</p>

    <item><p>The <code>style</code> attribute takes a space-separated list of

  <p>Use <code>em</code> to stress a word in a sentence:</p>

  <example>
    <code><![CDATA[
You should <em>never</em> run a graphical application as root.
]]></code>
    <p>You should <em>never</em> run a graphical application as root.</p>
  </example>

  <p>Use <code>em</code> to mark the first occurance of a term:</p>

  <example>
    <code><![CDATA[
Note that <em>accelerators</em> are different from <em>mnemonics</em>.
]]></code>
    <p>Note that <em>accelerators</em> are different from <em>mnemonics</em>.</p>

  <title>Processing Expectations</title>
  <p>Emphasized text is traditionally presented in an italic or oblique font.
  Italic and oblique fonts stress a portion of text without making it stand
  out.  By contrast, bold text tends to draw the eye, which can be distracting
  when reading long passages of text.  In scripts without a distinction between
  roman and italic type styles, it may still be possible to use an oblique font
  or some other font variation.  Bold text may be used if necessary.</p>
  <p>Underlining should be avoided completely, since it hurts the legibility
  of the text.  This problem is especially pronounced in scripts which place
  diacritical marks below the text.  In these scripts, underlining can render
  the text completely illegible.</p>

<section id="comparison">
  <title>Vergleich mit anderen Formaten</title>
  <p>The <code>em</code> element is similar to the
  <code href="http://www.docbook.org/tdg/en/html/emphasis.html">emphasis</code>
  element in DocBook.  Athough DocBook does not normatively specify a means of
  controlling the presentation, most DocBook display tools allow writers to
  set the <code>role</code> attribute to <code>bold</code> or <code>strong</code>
  to specify bold text.  No such recommendation is made for Mallard.</p>
