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. | |
