The problem with the BB Contract Specification, which appear to be empty, is caused by the fact that the functionality for using XSL transformation of XML documents in Microsoft's Internet Explorer 5.x is not compliant with the latest W3C standards. Microsoft has therefore released a update of their XML library.
