The following tables compare XHTML 1.1 compatibility and support for a number of layout engines.
Contents
XHTML 1.1 which is mainly a modularization of XHTML 1.0, is composed of 20 element modules (7 of which are submodules), including the additional Ruby Annotation Module, and two attribute modules (Server-side Image Map Module and Intrinsic Events Module).
Engine nomenclature
Rather than the names of web browsers and HTML to PDF converters, the names of the underlying engines are used. Some of the software and online converters that use the various engines are listed below.
Values
Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.
