In this zip bundle there are some complex REF^I12 example messages.

There are examples for two Referral profiles: 

Level 1 - containing a single ORC/OBR group and a PDF display segment.

Each are in their own directory
 .\Level 1\1\
 .\Level 1\2\

In Level 1 examples, only the PDF AUSPDI OBX display segments in the example should be viewable in receiving software that is compliant with Level 1. 
(That is all other display segments in the example should be successfully ignored by non Level 2 compliant viewers)
 
 Expectations of the displays are provided in the Expected Displays subfolder of each example.
