Hi Timothy,
The sample covers both cases, the schema allows also the xi:include
element (in the case when XInclude processing is disabled and this is
needed also for content completion) and the content that replaces the
xi:include (the additional xml:base attribute that appears on the
included elements).
Thanks for the info. I'm not sure what that second part means; "and
the content that replaces the xi:include". Would you explain this a
little more?
When some element is included than an xml:base attribute appears on that
element pointing to the file it was included from. In the second part I
meant that the sample schema defines the xml:base attribute. You can see
that very easily if you run the document through an identity XSLT
transformation, for instance:
test.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:template match="/">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
applied on
test.xml
<?xml version="1.0" encoding="UTF-8"?>
<scopes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="test.xsd">
<scope name="test"/>
<include xmlns="http://www.w3.org/2001/XInclude"; href="included.xml"/>
<scope name="another scope"/>
</scopes>
included.xml
<?xml version="1.0" encoding="UTF-8"?>
<scope name="inlcudedScope">
This is an <important>included</important> scope.
</scope>
gives (note the xml:base attribute on the included scope element)
<?xml version="1.0" encoding="UTF-8"?><scopes
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="test.xsd">
<scope name="test"/>
<scope name="inlcudedScope"
xml:base="file:/C:/Documents%20and%20Settings/Administrator.SPEECH/Desktop/xincludeWithSchema/included.xml">
This is an <important>included</important> scope.
</scope>
<scope name="another scope"/>
</scopes>
Also, I have XInclude processing turned on. However, the main
document still validates even with an error in the included document.
Is this expected behavior? Would I have to do something like use
XSLT to actually replace the included document in to the main
document to do a single full validation?
Hmmm... If I edit the included.xml file and rename important as
important2 then I get the following error:
SystemID: [...]\included.xml
Location: 5:15
Description: cvc-complex-type.2.4.a: Invalid content was found starting
with element 'important2'. One of '{important}' is expected.

No, you should not need to do anything than enabling the XInclude
processing to perform a validation of the document that results after
XIncludes are processed against an XML Schema. Note that the validation
againt DTDs is different, in that case each document is validated
against its DTD without expanding the XInclude elements.
Best Regards,
George
