Zander, thank you for trying hard to ensure backwards compatibility. Some of these ".dia" files are filed away and then pulled out years later when an enhancement is needed. I don't even know what version originally created them. I noticed one had a reference to xmlns:dia and http://www.lysator.liu.se/~alla/dia/ but that site doesn't exist anymore. I tried to look at the "DummyDB.dia" file here, and it looks like binary. but the ".dia" filie I have is XML. I don't understand.
