 2   The <tt class="literal">IMPORT</tt> tag, which must be placed inside a <tt class="literal">RULES</tt> tag, loads all rules defined in a given ruleset into the current ruleset; in other words, it has the same effect as copying and pasting the imported ruleset.
 3  </p><p>
 4   The only required attribute <tt class="literal">DELEGATE</tt> must be set to the name of a ruleset. To import a ruleset defined
 5   in the current mode, just specify its name. To import a ruleset
 6   defined in another mode, specify a name of the form
 7   <tt class="literal"><i class="replaceable"><tt>mode</tt></i>::<i class="replaceable"><tt>ruleset</tt></i></tt>.
 8   Note that the first (unnamed) ruleset in a mode is called
 9   &#8220;<span class="quote">MAIN</span>&#8221;.
10  </p><p>
11   One quirk is that the definition of the imported ruleset is not copied to the location of the <tt class="literal">IMPORT</tt> tag, but rather to the end of the containing ruleset. This has implications with rule-ordering; see <a href="mode-tag-rules.html#rule-ordering" title="Rule Ordering Requirements">the section called &#8220;Rule Ordering Requirements&#8221;</a>.

13   Here is an example from the PHP mode, which extends the inline JavaScript highlighting to support embedded PHP:
14  </p><table border="0" bgcolor="#E0E0E0"><tr><td><pre class="programlisting">
15   &lt;RULES SET="JAVASCRIPT+PHP"&gt;
16
17   &lt;SPAN TYPE="MARKUP" DELEGATE="php::PHP"&gt;
18       &lt;BEGIN&gt;&amp;lt;?php&lt;/BEGIN&gt;
19       &lt;END&gt;?&amp;gt;&lt;/END&gt;
20   &lt;/SPAN&gt;
21   
22   &lt;SPAN TYPE="MARKUP" DELEGATE="php::PHP"&gt;
23       &lt;BEGIN&gt;&amp;lt;?&lt;/BEGIN&gt;
24       &lt;END&gt;?&amp;gt;&lt;/END&gt;
25   &lt;/SPAN&gt;
26   
27   &lt;SPAN TYPE="MARKUP" DELEGATE="php::PHP"&gt;
28       &lt;BEGIN&gt;&amp;lt;%=&lt;/BEGIN&gt;
29       &lt;END&gt;%&amp;gt;&lt;/END&gt;
30   &lt;/SPAN&gt;
