Most do. Some of them do support null end tags in HTML correctly and then litter XHTML-as-text/html documents with displayed greater than signs. Besides, complying with, or at least extracting any sense from Appendix C is hard. It is non-normative, mostly phrased to avoid giving anything that looks like a requirement and gives contradictory advice (e.g. advising against using processing instructions altogether in C1 and then advising not to use stylesheets without them in C14). -- David Dorward http://dorward.me.uk
