OPENSim software uses .XML to import objects/groups.

For example, someone might create a chair in OPENsim (the software that runs Second Life and other VR Worlds) and export it out. This can then be uploaded into Second Life and used or sold/passed to another user. The resulting file might be called 'chair.xml'
