I am using Xerces 2.7.1.
A schema associated with one namespace is trying to import multiple
schemas that are each associated with another namespace. Only the first
in a sequence of imports appears to be processed. (The same thing
happens if the sequence contains both includes and imports; the first
such element, whether an import or include, is the only one that appears
to be processed.)
When types from the schemas associated with all but the first import or
include are encountered in the top level schema, I see a lot of
unresolved references.
A sequence of includes works properly, by the way. The issue is
encountered only if imports are involved.
I created a simplified version of what I am seeing. I have 3 schemas,
all in the same directory.
Top.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
targetNamespace="topLevelNS" elementFormDefault="qualified"
attributeFormDefault="unqualified" xmlns="topLevelNS"
xmlns:b = "bottomLevelNS">
<xs:import namespace="bottomLevelNS" schemaLocation="A.xsd"/>
<xs:import namespace="bottomLevelNS" schemaLocation="B.xsd"/>
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="A" type="b:AType"/>
<xs:element name="B" type="b:BType"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
A.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
targetNamespace="bottomLevelNS" elementFormDefault="qualified"
attributeFormDefault="unqualified" xmlns="bottomLevelNS">
<xs:simpleType name="AType">
<xs:restriction base="xs:string"/>
</xs:simpleType>
</xs:schema>
B.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
targetNamespace="bottomLevelNS" elementFormDefault="qualified"
attributeFormDefault="unqualified" xmlns="bottomLevelNS">
<xs:simpleType name="BType">
<xs:restriction base="xs:string"/>
</xs:simpleType>
</xs:schema>
When I validate Top.xsd, I see:
ERROR - Line 11 [42] {Top.xsd}: src-resolve: Cannot resolve the name
'b:BType' to a(n) 'type definition' component.
When I change the order of the imports, I see that b:AType is not
resolved instead.
I am obviously not understanding something here, since I believe that
Top.xsd is valid. Would someone please help me?
Thanks,
Lisa
