However, lists and unions have the ur-type definition as a base. And, shouldn't the following rules be stated? If the {variety} is list, then the {final} of the {item type definition} must not contain list. If the {variety} is union, then the {final} of all the {member type definitions} must not contain union. See http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001AprJun/0294.html Henry's response: http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001AprJun/0296.html 5815 1 sandygao 2005-09-07 20:09:56 +0000 The WG determined that the commentator is correct, and bullet 4 of Section 3.14.6 of Structures need to be modified to include the following rules: - If the {variety} is list, then the {final} of the {item type definition} must not contain list. - If the {variety} is union, then the {final} of all the {member type definitions} must not contain union.
