4 : * XHTML 1.1 Legacy module defines elements that were previously
5 : * deprecated.
6 : *
7 : * @note Not all legacy elements have been implemented yet, which
8 : * is a bit of a reverse problem as compared to browsers! In
9 : * addition, this legacy module may implement a bit more than
10 : * mandated by XHTML 1.1.
11 : *
12 : * This module can be used in combination with TransformToStrict in order
13 : * to transform as many deprecated elements as possible, but retain
14 : * questionably deprecated elements that do not have good alternatives
15 : * as well as transform elements that don't have an implementation.
16 : * See docs/ref-strictness.txt for more details.
