[dsdl-comment] Re: Problem with specifying the <Book> section occur only within the <soap:Body> element

Hi Roger,

The NVDL script will create two validation candidates from the sample
document, one containing the whole document and that will be validated
against the soap.xsd schema and one containing the elements from the
http://www.books.com namespace and that will be validated against the
Book.rng schema.

The error reported by oNVDL is related to the first validation, when the
whole document is validated against the soap.xsd schema. As it is
defined the Body element can contain any element from other namespaces
but the default value for xs:any/@processContents is strict which means
that those elements need to be valid. If you specify a value of lax or
strict fot the processContents attribute then the whole document will be
validated by the soap.xsd schema:

     <xsd:element name="Body">
         <xsd:complexType>
             <xsd:choice>
                 <xsd:any processContents="lax"
                          namespace="##other" maxOccurs="unbounded"/>
                 <xsd:element ref="Fault"/>
             </xsd:choice>
         </xsd:complexType>
     </xsd:element>

Best Regards,
George
