Thanks for the reply. With VPP Modeler v11, the XMI 1.2 that I exported with VPP works when importing back into VPP and StarUML 1. I can provide you the installer for StarUML 1 or you can download from https://staruml.en.softonic.com/download as I checked that it is the same version which is 5.0.2.1570. StarUML may not be able to create components that it does not understand but as long as it is able to create classes/diagrams out of the parts that it understands then that would unblock me and will let me use the latest VPP version with my employer.
