Xerces SAX2 parser can not skip xs:any if xsi:nil is used in xml

           Summary: Xerces SAX2 parser can not skip xs:any if xsi:nil is
                    used in xml
           Product: Xerces-C++
           Version: 2.4.0
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Validating Parser (Schema) (Xerces 1.5 or up only)
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: andy.ding@ericsson.com


We're using Xerces-C++ version 2.4.0. Now we found an error about xerces SAX2
parser can not skip xs:any type if "xsi:nil=true" is used in xml.

As you can see, in following "note.xml", the element "school" should be
validated by another schema file defining this element, not by the schema file
defining "xs:any".

The schema example:

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.w3schools.com"
elementFormDefault="qualified"
targetNamespace="http://www.w3schools.com">
<xs:element name="note">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="to" type="xs:string"/>
        <xs:element name="from" type="xs:string"/>
        <xs:any namespace="##any" processContents="skip" maxOccurs="unbounded"/>
      </xs:sequence>
    </xs:complexType>
</xs:element>

</xs:schema>

The xml example:

<?xml version="1.0"?>
<note xmlns="http://www.w3schools.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3schools.com note.xsd">
<to>Tove</to>
<from>Jani</from>
<school>
  <student xsi:nil="true"/>
</school>
</note>

The error message:

Error at file 10000, line 15, char 8
  Message: Element note with attribute xsi:nil=true must be empty
