Import, Include and namespace

Import, Include and namespace

2003-07-31 - By Inns, Jeff

This is not exactly a Xerces question but a general XML Schema question.

If a schema ("my") imports two schemas ("a" and "b") and "a" & "b" include
"c", does "c" belong to the two different namespaces in "my"? "my", "a" and
"b" have different targetNamespaces.

Schema "my":

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="file://c:/name-space"
xmlns:b="file://c:/name-space/b" xmlns:a="file://c:/name-space/a"
xmlns:name-space="file://c:/name-space"
xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:import namespace="file://c:/name-space/a"
schemaLocation="file://c:/name-space/a/a.xsd"/>
<xs:import namespace="file://c:/name-space/b"
schemaLocation="file://c:/name-space/b/b.xsd"/>
<xs:element name="root">
</xs:element>
</xs:schema>

Schema "a":

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="file://c:/name-space/a"
xmlns="file://c:/name-space/a" xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:include schemaLocation="file://c:/name-space/c/c.xsd"/>
<xs:element name="a">
</xs:element>
</xs:schema>

Schema "b":

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="file://c:/name-space/b"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="file://c:/name-space/b"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:include schemaLocation="file://c:/name-space/c/c.xsd"/>
<xs:element name="b">
</xs:element>
</xs:schema>

Schema "c":

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="c">
</xs:element>
</xs:schema>
