title: HL7 v2 structure
body: <p>I have a problem with how many instances in the image below are of each segment. I know that the MSH is 1 and the NTE is 0 to many but in the next Segments I am not sure how to deal with that. Is it 1 or 1 to many for ORC? 
  Can anybody tell me the right number of each segment? That would be great.</p>
