 A match pattern is essentially a URL
-that begins with <code>http</code>, <code>https</code>,
-<code>file</code>, or <code>ftp</code>,
+that begins with a permitted scheme (<code>http</code>,
+<code>https</code>, <code>file</code>, or <code>ftp</code>),
 and that can contain '<code>*</code>' characters.
+The special pattern
+<code>&lt;all_urls&gt;</code> matches any URL
+that starts with a permitted scheme.
 Each match pattern has 3 parts:</p>

 <ul>
   <li> <em>scheme</em> —
     for example, <code>http</code> or <code>file</code>
