I'm not sure if this is a CrossOver + EA issue or just a plain EA issue (as I don't have Windows to test & verify).
Exporting a package to XMI (either 1.1 or 2.1) adds " " to the end of each line:
<XMI xmlns:UML="omg.org/UML1.3" xmi.version="1.1" timestamp="2014-05-30 22:16:52">
Can anyone else verify the behavior (both under CrossOver and/or Windows)?
