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" /> -- David A.
