> Key: XERCESJ-1584
> URL: https://issues.apache.org/jira/browse/XERCESJ-1584
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Datatypes
> Affects Versions: 2.11.0
> Reporter: Radu Coravu
> Assignee: Mukul Gandhi
> Fix For: 2.12.0
>
> Original Estimate: 3h
> Remaining Estimate: 3h
>
> I have 3 schemas like:
> 1.xsd:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified" targetNamespace="tns">
> <xs:complexType name="ct"/>
> </xs:schema>
> 2.xsd:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified" targetNamespace="tns">
> <xs:include schemaLocation="1.xsd"/>
> </xs:schema>
> 3.xsd:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified" targetNamespace="tns" xmlns="tns">
> <xs:redefine schemaLocation="2.xsd">
> <xs:complexType name="ct">
> <xs:complexContent>
> <xs:extension base="ct">
> <xs:attribute name="attr" use="required"/>
> </xs:extension>
> </xs:complexContent>
> </xs:complexType>
> </xs:redefine>
> <xs:element name="el" type="ct"/>
> </xs:schema>
> When validating "3.xsd" Xerces reports it as valid.
> When validating "3.xsd" Saxon 9 EE reports:
> The redefined complex type was found, but not in the schema document
> referenced by the schemaLocation attribute of the containing <xs:redefine>
> element. This is not allowed by the XSD specification. However, Saxon does
> not currently enforce this rule.
> There are two problems:
> 1) In Xerces 2.9.0 this construct used to work, the complex type "ct" was
> redefined.
> So if you had an XML instance like:
> <el xmlns="tns"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="tns
> file:/C:/Users/radu_coravu/Desktop/testWarning/3.xsd"/>
> Xerces 2.9.1 reported an error, that the attribute "attr" was absent.
> Xerces 2.11.0 no longer reports any error.
> 2) If you want to keep the current behavior of ignoring completely the
> redefine, then you should at least report a problem when validating the
> "3.xsd" schema like Saxon EE does.
