Hello Roger,

My suggestion is to follow the steps below:
- select "PreferredRouteRouteType" in "Enumerations.xsd", then right click and invoke "Search" > "Search References in..."
- choose "Working sets" > "New working set" > Enter > "Add resources" > "Folders" and, via the "Choose" dialog-box, choose the directory containing your entire schema hierarchy
- press the "Search" button and check the dedicated tab in the "Results" view
- the results should be presented as links to the elements you are interested in, from the entire schema hierarchy.

I checked the suggested procedure on a very simple example and it worked well.
I have attached the respective test archive ("test-XSD.zip").

I have also investigated another method to achieve the results you want.
You can use the "Component Dependencies" view in Oxygen XML Editor to analyze and visualize component dependencies in your schema.
This feature allows you to see where a selected component (such as an element or type) is used throughout the schema hierarchy.

To use it:
- right-click the desired component in the editor or Outline view
- select the "Component Dependencies" action from the contextual menu.
A table will display all references to the selected component, making it easy to track dependencies and usages.
For more details, see the documentation on the "XML Schema Component Dependencies View".

Regards,

Teo
