> I've been using the following XML Schema validation example, for this issue.
> XML Schema document,
> <?xml version="1.0"?>
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
>                     elementFormDefault="qualified"
>                     attributeFormDefault="qualified"
>                     targetNamespace="http://ns0">
>       <xs:element name="X">
>            <xs:complexType>
>                <xs:sequence>
>                    <xs:element name="a" type="xs:string"/>
>                </xs:sequence>
>                <xs:attribute name="att1" type="xs:integer" use="required"/>
>            </xs:complexType>
>        </xs:element>
> </xs:schema>
> XML instance document, that's validated with above mentioned XML Schema document,
> <?xml version="1.0"?>
> <X xmlns="http://ns0" att1="105">
>     <a>hello</a>
> </X>
> Upon doing, above mentioned XML Schema validation, XercesJ currently produces following two error messages,
> cvc-complex-type.3.2.2: Attribute 'att1' is not allowed to appear in element 'X'.
> cvc-complex-type.4: Attribute 'att1' must appear on element 'X'.
> I find, above mentioned error messages little bit confusing.
> I propose that, the second error message cited above should contain namespace information as well, something like following,
> cvc-complex-type.4: Attribute 'att1' belonging to namespace 'http://ns0', must appear on element 'X'.
