 2        <code class="literal">RULES</code> tag, highlights text between a start and end
 3        string. The start and end strings are specified inside child elements of
 4        the <code class="literal">SPAN</code> tag. The following attributes are
 5        supported:</p><div class="itemizedlist"><ul type="disc"><li><p><code class="literal">TYPE</code> - The token type to highlight the
 6                span with. See <a class="xref" href="mode-syntax-tokens.html" title="Token Types">the section called &#8220;Token Types&#8221;</a> for a list

10                <code class="literal">TRUE</code>, the span will only be highlighted if
11                the start sequence is the first non-whitespace text in the
12                line.</p></li><li><p><code class="literal">AT_WORD_START</code> - If set to
13                <code class="literal">TRUE</code>, the span will only be highlighted if
14                the start sequence occurs at the beginning of a word.</p></li><li><p><code class="literal">DELEGATE</code> - text inside the span will be
15                highlighted with the specified ruleset. To delegate to a ruleset
16                defined in the current mode, just specify its name. To delegate
17                to a ruleset defined in another mode, specify a name of the form
18                <code class="literal"><em class="replaceable"><code>mode</code></em>::<em class="replaceable"><code>ruleset</code></em></code>.
19                Note that the first (unnamed) ruleset in a mode is called
20                &#8220;<span class="quote">MAIN</span>&#8221;.</p></li><li><p><code class="literal">MATCH_TYPE</code> - Controls how the start and
21                end of the sequence will be highlighted.

22                for escaping characters. The first character following the escape
23                sequence is not considered as input for syntax highlighting,
24                thus being highlighted with rule's token.
25                </p></li><li><p><code class="literal">NO_LINE_BREAK</code> - If set to

30        <code class="literal">AT_WHITESPACE_END</code> and

32        <code class="literal">BEGIN</code> and <code class="literal">END</code> elements. Setting
33        these attributes to the same value on both elements has the same effect
34        as setting them on the <code class="literal">SPAN</code> element.</p><p>Here is a <code class="literal">SPAN</code> that highlights Java string
