Hi Junedi,
can you provide a screenshot of your pub.schena:validate configuration?
Provide screenshots of the generatted DocType and schema as well.
Most likely you will have to create a DocType node in Designer by using the xsd as a source.
You can then validate against the schema node which has been created along side with the document(s).
See IS Built-In Services Guide for further informations.
Regards,
Holger
