See: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2001May/0027.html Henry's response: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2001Jun/0017.html - In addition, in a separate email, the commentator points out a problem with wildcard subset, "##other" and absent. For example, if wildcard "w2", say, equals "absent", and wildcard "w1" is "not some-uri", then, "absent" is allowed by "w2", not allowed by "w1", and yet the rules for subset indicate that "w2" is a subset of "w1".
