Hi David,
Thanks for pointing out this problem. "use" and "fixed" were ignored if an
attribute declarations refers to an attribute from another namespace.
Now it's fixed in CVS. So grab the latest version and try again.

<driggs@asset. cc:

when importing schema namespace
08/07/2001

Please respond
to
xerces-j-dev
I'm attempting to validate an instance document against
a slightly complicated schema which includes and imports
several smaller ones. I've noticed that attributes
specified use="required" that are referenced from an
imported schema/namespace aren't enforced as I'd expect.
I've included boiled-down examples to better illustrate
below. I'm using JDK 1.3.1 and Xerces-J 1.4.2 and am
trying to validate using one of the included samples,
java -classpath xerces.jar;xercesSamples.jar dom.DOMCount -svnf
instance.xml
Any pointers or feedback would be greatly appreciated!
Thanks,
David A. Riggs

The main schema:
-----------------------------
<?xml version = "1.0" encoding = "UTF-8"?>
<xsd:schema xmlns = "http://birch.asset.com/example";
targetNamespace = "http://birch.asset.com/example";
xmlns:xsd = "http://www.w3.org/2001/XMLSchema";
xmlns:driggs="http://driggs.asset.com";>
<!-- Import namespace and global attribute from second schema -->
<xsd:import namespace = "http://driggs.asset.com";
schemaLocation = "importedSchema.xsd" />
<xsd:element name="root">
<xsd:complexType>
<!-- This attribute is required, and the parser handles it
properly
-->
<xsd:attribute name="LocalRequiredAttribute" use="required"
/>
<!-- This referenced attribute is required, but the parser doesn't
catch it -->
<xsd:attribute ref="driggs:GlobalRequiredAttribute" use="required"
/>
</xsd:complexType>
</xsd:element>
</xsd:schema>
--------------------------------
The imported schema containing the globally defined attribute:
---------------------------------
<?xml version = "1.0" encoding = "UTF-8"?>
<xsd:schema xmlns = "http://driggs.asset.com";
targetNamespace = "http://driggs.asset.com";
xmlns:xsd = "http://www.w3.org/2001/XMLSchema";>
<xsd:attribute name="GlobalRequiredAttribute" />
</xsd:schema>
-----------------------------------
The instance document - should produce errors when validated
since GlobalRequiredAttribute is not present, xerces lists
no errors when parsed and validated:
------------------------------------
<?xml version = "1.0" encoding = "UTF-8"?>
<root xmlns="http://birch.asset.com/example";
xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation = "http://birch.asset.com/example example.xsd"
LocalRequiredAttribute="blah" />
