That phrase is coming out in an agreed erratum (but it's not being
replaced with descendants, so the point still stands).

XSV flags errors for both the child and the grandchild.

I think your schema is precisely the way the W3C XML Schema REC
intended for this to be achieved -- it appears the REC needs
clarification in this area, as evidently Xerces C++ and XSV disagree.
I'd be interested to hear from other implementors wrt this example.
