Hi Jeff, Thanks for your input.
(1) Indirect Circular attributeGroup reference As you found out, this is a bug of the spec, not Xerces :-) I have a fix for this, but we are working on 1.4.3 release at the same time. So I'm not sure whether this fix will be in 1.4.3. (2) Attribute Ref doesn't work? Since default namespace doesn't apply to attributes (from the namespace spec), you need to specify namespace for attribute "foo" explicitly: <root xmlns="http://www.example.com"; xmlns:myns="http://www.example.com"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.example.com att.xsd" myns:foo="test"/> Cheers, Sandy Gao Software Developer, IBM Canada (1-416) 448-3255 [EMAIL PROTECTED] [EMAIL PROTECTED] thlink.net To: <[EMAIL PROTECTED]> cc: 08/17/2001 Subject: Attribute References and Groups 12:40 AM Please respond to xerces-j-user I have been using Xerces like mad lately and it is great!-- I ran across what appear to be a couple of bugs-- hopefully someone can confirm: (1) Indirect Circular attributeGroup reference att.XML ====== <?xml version="1.0"?> <root xmlns="http://www.example.com"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.example.com att.xsd"/> att.XSD ====== <?xml version="1.0"?> <schema xmlns="http://www.w3.org/2001/XMLSchema"; xmlns:target="http://www.example.com"; targetNamespace="http://www.example.com"; elementFormDefault="qualified"> <!-- Indirect circular reference --> <attributeGroup name="AttGroup1"> <attributeGroup ref="target:AttGroup2"/> </attributeGroup> <attributeGroup name="AttGroup2"> <attributeGroup ref="target:AttGroup1"/> </attributeGroup> <element name="root"> <complexType> <attributeGroup ref="target:AttGroup1"/> </complexType> </element> </schema> === The src for attributeGroup representation point 3 does not disallow indirect resolution per se-- but it should be implied. It looks as though the parser is trying to use the declaration when it should raise an error. It correctly raises an error when the attributeGroup refers to itself. [1] (2) Attribute Ref doesn't work? att2.XML ======= <?xml version="1.0"?> <root xmlns="http://www.example.com"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.example.com att.xsd" foo="test"/> att2.XSD ======= <?xml version="1.0"?> <schema xmlns="http://www.w3.org/2001/XMLSchema"; xmlns:target="http://www.example.com"; targetNamespace="http://www.example.com"; elementFormDefault="qualified"> <!-- Indirect circular reference --> <attribute name="foo" type="string"/> <element name="root"> <complexType> <attribute ref="target:foo"/> </complexType> </element> </schema> Error ==== [Error] Attribute "foo" must be declared for element type "root". line 5 column 19 - att2.xml Foo is declared-- it uses the ref model to utilize the global declaration.
