Since you are building the DXL-stream manually you need to supply all necessary information. This includes a reference to the schema to be used.

My trick to avoid hard coded information was to create a short DXLExport and read the first two lines. Then I use these lines to start my manually build stream.

Another hint: in your oops section first test for the existance of the dxlimporter object. Otherwise you might get into a loop.
