Example 3: Specification: Nested repetition (Solar system)
This example from the original specification shows how to use nested repetition elements:
The previous example does not demonstrate nested repeat blocks, reordering repetition blocks, and inserting new repetition blocks in the middle of the existing sequence, all of which are possible using the facilities described above. This example shows nested repeats.
Note that to uniquely identify each nested repeat (which is required since the add buttons are dependent on IDs to specify which template should have a block added), the IDs of the nested templates are specified in terms of the ancestor template's ID, using the index substitution feature.
