But in Appendix A. SML-IF Schema: <xs:complexType name="schemaBindingType" mixed="false"> <xs:sequence> <xs:element ref="smlif:namespaceBinding"/> <xs:element name="documentAlias" type="smlif:uriType" minOccurs="0" maxOccurs="unbounded"/> <xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> <xs:anyAttribute namespace="##other" processContents="lax"/> </xs:complexType> Note that the reference to "namespaceBinding" has no min/maxOccurs specified, and minOccurs=0 is specified on "documentAlias". So obviously 4.1 and appendix A don't agree. What's intended? I think both <namespaceBinding> and <documentAlias> should be '*', that is minOccurs=0, maxOccurs=unbounded. For <namespaceBinding>, because a schema can have more than one namespaces, we can't limit the number of <namespaceBinding> to exactly 1. For <documentAlias>, allowing minOccurs=0 means that the producer can write <schemaBindings> <schemaBinding> <namespaceBinding namespace="ns" aliases="v1.xsd"/> </schemaBinding> <schemaBinding> <namespaceBinding namespace="ns" aliases="v2.xsd"/> </schemaBinding> </schemaBindings> That is, they can group schema documents in meaningful ways (e.g for different versions) without having to specify instance documents. This is useful when only schema documents are transmitted in the IF package. 21471 1 pratul.dublish 2008-08-07 19:05:03 +0000 Resolution in 8/7 call both <namespaceBinding> and <documentAlias> should be '*', that is minOccurs=0, maxOccurs=unbounded." Pseudo-schema and normative schema must be changed to agree with this proposal. 21518 2 virginia.smith 2008-08-12 23:39:15 +0000 Fixed per comment #1.
