This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
In various places in the Structures spec, statements like the following appear: "type definition A must be validly derived from type definition B given its {prohibited substitutions}, as defined in Type Derivation OK (Complex) (213.4.6) (if it is a complex type definition), or given the empty set, as defined in Type Derivation OK (Simple) (213.14.6) (if it is a simple type definition)." Questions: Which type does each reference of "it" refer to in the paragraph above? There is no constraint for the case where A is a simple type and B is a complex type; how do we check whether the type "string" is a valid derivation from "anyType"? See bullet 2 from: http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001OctDec/0049.html
The WG resolved to classify R-79 as an error, at the March 14 telecon
Discussed at 2007-05-18 telecon. Determined this issue also applies to schema 1.1, and it is an editorial issue. Marking it accordingly.
Fixed in the course of other revisions.
