Hide the package name of a foreign element when displayed onto a diagram

How to hide a package name of an element when it is displayed on a diagram which is situated outside the element package?

By default in EA, the package name is displayed whenever an element is added to a diagram if it is not situated in the same package than the diagram.

To hide the package name displayed onto a diagram for an element, open the properties dialog of the desired diagram by selecting the Properties... menu option of the context menu (right-click on the diagram once displayed) or directly by pressing the keyboard shortcut F5.

Next, select the Diagram tab and uncheck the option Show Namespace.
Finally, click on the OK button to apply the change.
