<br>
Each byte of text will be contained in exactly one of the items in the returned vector. The generated vector of items will be in logical order (the start offsets of the items are ascending).<p>
<em>cached_iter</em> should be an iterator over <em>attrs</em> currently positioned at a range before or containing <em>start_index</em>; <em>cached_iter</em> will be advanced to the range covering the position just after <em>start_index</em> + <em>length</em>. (i.e. if itemizing in a loop, just keep passing in the same cached_iter). </td>
