This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Is the itemType of a list meant to be of "atomic" type ONLY or of EITHER "atomic" OR "union" type? Sections 2.5.1.2 and 4.1.2.2 of Datatypes appear to be contradictory. See http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001AprJun/0209.html
It was intended that the itemType be either atomic or union. An erratum E2-15 was be added to clarify this.
