>          Components: SAX/SAX2

> Xerces doesn't check if attributes from
> "http://www.w3.org/XML/1998/namespace" namespace which can have default value
> (e.g., xml:space) are directly specified in the data. So it leads to xml:space
> duplication in attributes list during startElement event.
> Sample .xml & .xsd are attached. 
> For schema fragment
> ...
>             <xsd:element name="name">
>                 <xsd:complexType>
>                     <xsd:simpleContent>
>                         <xsd:extension base="xsd:string">
>                             <xsd:attribute ref="xml:space"/>
>                         </xsd:extension>
>                     </xsd:simpleContent>
