<code class="literal">RULES</code> tag, highlights text between a start and end
string. The start and end strings are specified inside child elements of
the <code class="literal">SPAN</code> tag. The following attributes are
supported:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p><code class="literal">TYPE</code> - The token type to highlight the
span with. See <a class="xref" href="mode-syntax-tokens.html" title="Token Types">the section called “Token Types”</a> for a list
of token types.</p></li><li class="listitem"><p><code class="literal">AT_LINE_START</code> - If set to
<code class="literal">TRUE</code>, the span will only be highlighted if
the start sequence occurs at the beginning of a line.</p></li><li class="listitem"><p><code class="literal">AT_WHITESPACE_END</code> - If set to
<code class="literal">TRUE</code>, the span will only be highlighted if
the start sequence is the first non-whitespace text in the
line.</p></li><li class="listitem"><p><code class="literal">AT_WORD_START</code> - If set to

the start sequence occurs at the beginning of a word.</p></li><li class="listitem"><p><code class="literal">DELEGATE</code> - text inside the span will be
highlighted with the specified ruleset. To delegate to a ruleset
defined in the current mode, just specify its name. To delegate
to 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></li><li class="listitem"><p><code class="literal">MATCH_TYPE</code> - Controls how the start and

for escaping characters. The first character following the escape
sequence is not considered as input for syntax highlighting,
thus being highlighted with rule's token.
