Adding a repeating mapping

Mapping repeating structures is slightly different from mapping single elements because of the nature of the elements or instances that are available for mapping. The following example shows a message tree node partially expanded.

message1
   |_ top
      |_ middle[]
         |_bottom[]
      |_ middle[1]
         |_bottom[]
         |_bottom[All]
         |_bottom[1]

In this example, an entry followed by [] is referred to as a repeatable node, one followed by [All] is referred to as an all node, and one followed by [1] is referred to as an instance element node.

There are two ways to create a mapping to a non repeatable (scalar) target for some form of aggregation:
