You can map ports to the following types of nodes:

Atomic node

A simple element or an attribute that has no children and is not divisible.

Multiple-occurring atomic node

A simple element or an attribute that occurs multiple times at the same location in the hierarchy.

Complex node

An element that contains other elements.

If the parent node does not have a location, the parent node receives the input group name as the location. When the parent node has a location, each node in the hierarchy level must have an output location from the same location.

You can map an input group name to a parent node in a hierarchy level. The Developer tool updates the location field for the parent node in the hierarchy. The Developer tool does not update the child nodes that belong to the group in the hierarchy. When you map input ports to the child nodes, each input port location must be the same location as the location parent node.

After you map an input group to a hierarchy level, you can change it later. You can click

or you can delete the lines between the Ports and the Operation area. To delete the lines, drag the pointer of the lines to select them. Click
