+     *     name component must be immediately preceded by the `\`<br/>
+     *     quoting character, to prevent interpretation as a component<br/>

+     *     represented, respectively, by `\n`, `\t`, `\b`, or `\0`.<br/>
+     * <br/>
+     *     (1c) If the `\` quoting character occurs outside the contexts<br/>
+     *     described in (1a) and (1b) above, the following character is<br/>
+     *     interpreted literally.  As a special case, this allows the<br/>

+     * <br/>

+     *  immediately follows. If no realm name element is included, the<br/>
+     *  local realm name is assumed.  The `/` , `:`, and null characters<br/>
