This appendix is informative, not normative.
The following properties were present in CSS2, but are not part of CSS 2.1: 'font-size-adjust', font-stretch, 'marker-offset', 'marks', 'orphans',, 'size',, 'text-shadow', 'widows'.
The CSS2 aural properties are now described in Appendix A and the following properties therefore do not appear in the table above: 'azimuth', 'cue', 'cue-after', 'cue-before', 'elevation', 'pause', 'pause-after', 'pause-before', 'pitch', 'pitch-range', 'play-during', 'richness', 'speak', 'speak-header', 'speak-numeral', 'speak-punctuation', 'speech-rate', 'stress', 'voice-family', 'volume'.
