Inverting structures can only move one structure node level at a time since all nodes are out of order for the result so this example requires three structure
copies to define the Reshaping operation. This makes it a good example of how the target structure drives the structure transformation process top to bottom and more
clearly demonstrates with three structure copies how the synchronizing between structure copies is performed.

Fast, reliable data access for ODBC, JDBC, ADO.NET and XML |
In the example of inversion in Figure 5, you will notice that the inversion logic accesses the source structure’s nodes from the bottom up retrieving from one node
from each structure level. First it moves the Project, then Employee, and finally Department nodes. It needs to correctly establish its synchronizing join link point
between each step as shown. This is a form of navigation.
