I propose adding to Schema Representation Constraint: Conditional Inclusion Constraints the rule: Any attribute that appears on an element information item in a ·schema document·, and whose name is in the schema versioning namespace, MUST have the local name minVersion, maxVersion, typeAvailable, typeUnavailable, facetAvailable, or facetUnavailable. 21480 1 David_E3 2008-08-08 15:59:06 +0000 <MSM> proposed amendment: for MUST read SHOULD, <MSM> and add a Note saying (roughly) "This is a SHOULD in order to preserve the ability of future versions of this spec to add new attributes to the namespace. <MSM> Processors are encouraged to issue warnings about attributes other than those named, but it is not, strictly speaking, an error." 21850 2 cmsmcq 2008-09-09 15:28:44 +0000 A change proposal intended to resolve this issue (and others) was adopted by the XML Schema WG on 5 September 2008. http://www.w3.org/XML/Group/2004/06/xmlschema-1/structures.b5904etc.html Accordingly, I am marking the issue RESOLVED.
