Multi schema XSDs node-soap

This may be on the same lines as this: node-soap multiple import schemas But I coudnt find the fix.

I have a WSDL which refers to one XSD and this XSD refers another one.

Parent.wsdl --> a.xsd -->b.xsd

node-soap is not able to create namespace for b.xsd due to which the soap request packet does not have entry for b.xsd types.

Please let me know how can I address this.

I have tried node-soap for 1 xsd scenario and it works perfectly fine.
