The data in this case includes a list of subjects. Each of the subjects has a list of exam papers and results. So this is quite a bit more complex See this in action here to log in to this demonstration and see a student document. Click on 'more...' to see the subject, papers and scores. Click edit to see how this information is edited. The structured fields are in bold type. So the address is split into separate fields. There are a couple of subjects, and under this there are some papers and results. You can add or remove subjects and results without leaving the page.
