<code class="literal">RULES</code> 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.</p><p>The only required attribute <code class="literal">DELEGATE</code> must be
set to the name of a ruleset. To import a ruleset defined in the current
mode, just specify its name. To import a ruleset defined in another
mode, specify a name of the form
<code class="literal"><em class="replaceable"><code>mode</code></em>::<em class="replaceable"><code>ruleset</code></em></code>.
Note that the first (unnamed) ruleset in a mode is called
<span class="quote">“<span class="quote">MAIN</span>”</span>.</p><p>One quirk is that the definition of the imported ruleset is not
copied to the location of the <code class="literal">IMPORT</code> tag, but rather
to the end of the containing ruleset. This has implications with
rule-ordering; see <a class="xref" href="mode-tag-rules.html#rule-ordering" title="Rule Ordering Requirements">the section called “Rule Ordering Requirements”</a>.</p><p>Here is an example from the PHP mode, which extends the inline
JavaScript highlighting to support embedded PHP:</p><pre class="programlisting">
<RULES SET="JAVASCRIPT+PHP">
<SPAN TYPE="MARKUP" DELEGATE="php::PHP">
<BEGIN><?php</BEGIN>
