Problem in validation of xml from multiple xsds stored in registry

Hello,

I have wriite  a mediator for validation, in my schema one <xsd:include>  is also there.

I created two entries in Integrated Registry
Schema/s1/File.xsd -  content of  child schema file
Schema/s1/OutputMessage.xsd -  content of  parent schema file

        Source validateSrc = SynapseConfigUtils.getStreamSource(synCtx.getEntry("Schema/s1/xmlFile"));
        ArrayList<String> schemaKeys = new ArrayList<String>();
        schemaKeys.add("Schema/s1/OutputMessage.xsd"); //parent xsd key from registry

//        schemaKeys.add("Schema/s1/File.xsd"); -  i tried using this also, but it is now working

//  in OutputMessage.xsd - i am tried with giving  "Schema/s1/File.xsd" as schemaLocation in the registry also but still no chance....

               StreamSource[] sources = new StreamSource[schemaKeys.size()];
                int i = 0;
                for (String propName : schemaKeys) {
                    sources[i++] = SynapseConfigUtils.getStreamSource(synCtx.getEntry(propName));
                }
            cachedSchema = factory.newSchema(sources);
            Validator validator = cachedSchema.newValidator();
            System.out.println("===before validate()");
            validator.validate(validateSrc);
            System.out.println("===after validate()");
        } catch (Exception e) {
               e.printStackTrace();
            // TODO: handle exception
               return false;
        }

I am receivng the following error - essentially it is not resolving the child xsd file.

org.xml.sax.SAXParseException: src-resolve: Cannot resolve the name 'bons0:File'
 to a(n) 'type definition' component.
        at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Un
known Source)
        at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source)

I have the respective files also...
