Hi all,
I shall cite following references, from XML Schema specifications.
XSD 1.1 structures spec,
3.16.2 XML Representation of Simple Type Definition Schema Components
<simpleType
final = (#all | List of (list | union | restriction | extension))
.....
XSD 1.0 structures spec,
3.14.2 (non-normative) XML Representation of Simple Type Definition Schema Components
<simpleType
final = (#all | List of (list | union | restriction))
.....
As you can see that, XSD 1.1 specifies "extension" as a possible value of "final" attribute of simpleType. Is "extension" a valid value of simpleType's attribute "final"? If yes, what is its semantics?
XSD 1.0 doesn't specify "extension" as a possible value of "final" attribute of simpleType.
But there's a following microsoft test case XSD document within W3C XSD 1.0 test suite (which specifies "extension" as a value of simpleType's attribute "final"),
<xs:schema xmlns:xs="
http://www.w3.org/2001/XMLSchema">
<xs:simpleType name="myType" final="extension">
<xs:restriction base="xs:string" />
</xs:simpleType>
<xs:complexType name="ct">
<xs:simpleContent>
<xs:extension base="myType">
<xs:anyAttribute />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
<xs:element name="myElement" type="ct" />
</xs:schema>
The corresponding test case definition, within W3C XSD 1.0 test suite is following,
<schemaTest name="stZ041">
<schemaDocument xlink:href=""> <expected validity="valid"/>
<current date="2006-12-22" status="queried" bugzilla="
http://www.w3.org/Bugs/Public/show_bug.cgi?id=4064"/>
<prior date="2006-07-16" status="accepted"/>
</schemaTest>
Is the above cited test case correct?
Any thoughts about above mentioned points, shall be helpful to know.
PS: to my enlightenment, the related w3c bugzilla entry for this test case cited above concludes, "WG agreed that either way the test is invalid".
