document formatting. Usually these instructions alter the
output formatting of specific DocBook elements, like table cells.
</p><p>To alter formatting globally it is better to set an
appropriate <a class="link" href="sec-custom.html#sec-param" title="Using XSL Parameters">stylesheet
parameter</a>.</p><p>Processing instructions are written
<code class="literal"><?</code><em class="replaceable"><code>name</code></em>
<em class="replaceable"><code>content</code></em> <code class="literal">?></code>. Most
often <em class="replaceable"><code>content</code></em> will have the form of one or more
XML attributes with a value, as follows:
<code class="literal"><?</code><em class="replaceable"><code>name</code></em>
<em class="replaceable"><code>attribute</code></em><code class="literal">="</code><em class="replaceable"><code>value</code></em><code class="literal">" ?></code>.</p><p>The list of the available Processing Instructions are given in <a class="xref" href="sec-pis.html" title="Appendix B.
