Yes. There are many example pedagogical as well as real application models.
With a modern version of BridgePoint (found here: https://s3.amazonaws.com/xtuml-releases/nightly-build/buildfiles.html), you can view and edit a number of other pedagogical and real-world applications.
In Help->Quick Start, you can quickly find the GPS Watch, which is still a teaching example but more complex.
On GitHub in xtuml/models you will find dozens of examples. Real-world applications include ‘vitalsigns’, ‘ec’ and ‘mail’.
