> If an element is nil (xsi:nil="true") and this element has child elements, Xercesc 3.1.0 does not report an error, although it should.
> According to this link:
> http://www.w3.org/TR/2004/REC-xmlschema-1-20041028/#cvc-elt
> an element that is nil may not have any content and any child elements.
> This behavior was also verified with Fujitsu's XWand XBRL Processor and Altovas XMLSpy, which both issue this error.
> It seems as if Xercesc tries to implement this behavior, given that the comments in SchemaValidator.cpp, line 129 are a direct copy of the mentioned web page:
> // if nillable, it's an error to have value
>         // XML Schema REC: Validation Rule: Element Locally Valid (Element)
>         // 3.2.1 The element information item must have no
>         // character or element information item [children].
>         //
> However, no error is issued in such a constellation.
> There is a related issue:
> If the first child element of the nilled value (which is *not* nil) has content, Xercesc issues the misguiding error message:
> Message: element '<name>' is nil and must be empty
> It seems, as if the nil-flag of the parent element is incorrectly set for the child element.
> For the second and all other child elements this is not the case (no error is reported).
> Steps to reproduce:
> Use the attached schema and instance document.
> Invoke the DOMCount-sample from the Xercesc-distribution like this:
> DOMCount.exe -v=always -s -n -f shiporder.xml
