Hello list,

I get a validation error an a XML document, that is - at least according 
to other XML tools - valid. For example <oxygen/> reports the attached 
document as valid.

The schemas are stripped down to the bare minimum to reproduce the error.

The error can be reproduced by invoking the xerces example:
 > DOMPrint -v=always -n -s invalid.xml
Error at file "/data/xml/XMLSchemas/invalid/invalid.xml", line 9, column 16
   Message: Unknown element 'bb:Status'

Version: Xerces-C 2.8.0.
XML File and Schemas are attached.

Any help is appreciated!

Cheers
Reiner
