XML validation problem (substitutionGr oup)

[Michael Skulsky]

Hi all,

I've got the following validation problem. There are 2 schemas and a
document:

-----------------------------------------------------------------
bar.xsd
======
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns:bar="urn: bar" targetNamespace ="urn:bar"
xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefa ult="qualified"
attributeFormDe fault="unqualif ied">

<element name="test">
<complexType>
<sequence>
<element name="qwe"/>
<element ref="bar:asd"/>
</sequence>
</complexType>
</element>

<element name="asd" abstract="true"/>
</schema>

foo.xsd
=====
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns:bar="urn: bar" xmlns:foo="urn: foo"
xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace ="urn:foo"
elementFormDefa ult="qualified" attributeFormDe fault="unqualif ied">

<import namespace="urn: bar" schemaLocation= "bar.xsd"/>

<element name="foo_asd" substitutionGro up="bar:asd"/>
</schema>
test.xml
======
<?xml version="1.0" encoding="UTF-8"?>
<test xmlns="urn:bar" xmlns:foo="urn: foo"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocat ion="urn:foo foo.xsd urn:bar bar.xsd">

<qwe/>
<foo:foo_asd/>

</test>
-----------------------------------------------------------------

The idea is that bar:asd is declared as abstract, and is substituted with
foo:foo_asd. All this validates perfectly in XML Spy and in any version of
MSXML, but the .NET parser comlains in the following way : The element
'urn:bar:test' has invalid child element 'urn:foo:foo_as d'. Expected
'urn:bar:asd'. An error occurred at , (5, 3).

It is obvious that we can't really have bar:asd, because it is abstract.
Does anybody have a clue what might be missing?
Thanks a lot in advance for any help!

I would try just referring to the foo schema in your xsi:schemaLocat ion
attribute, as in xsi:schemaLocat ion="urn:foo foo.xsd". Since foo.xsd
imports bar.xsd, I think this should work. Different processors handle
schemaLocation attributes differently; the XML Schema spec is flexible on
this topic.

Hope that helps,
Priscilla

Substitution groups across namespace did not work correctly in .net
framework 1.1. This works correctly in .net framework 2.0 beta2.

Thanks a lot for your help, in fact I've already found that out.
Both the example below and my actual XML files using this technology
validate perfectly using XmlSchemaSet object in .NET 2.0, but there seems to
be no way to have them validated in 1.1 with XmlSchemaCollec tion - except
for using MSXML of course.

Thanks again everybody for your help.
