This should be posed to the users group not the developers group.
Since the uninstall is non-interactive, the usual mantra would be if the user
has modified the XML file then you should leave it. From
http://msdn.microsoft.com/library/windows/desktop/hh749939, 5.4 Your app must
never block silent install/uninstall.
Uninstalling from Add/Remove programs will always invoke a silent uninstall.
Adding an uninstall shortcut is generally frowned upon, but more info can be
found

and
http://robmensching.com/blog/posts/2007/4/27/How-to-create-an-uninstall-shortcut-and-pass-all-the
but be aware that even if you provide an uninstall shortcut there is nothing
preventing the user from using the standard way of removing it.

Subject: [WiX-devs] Prompt to delete or preserve a file during uninstallation
Hi,
My application stores some contacts in an xml file.
While uninstalling I need to prompt the user to delete or preserve the contacts
file?
Based on the user input I should delete or preserve the file. How to achieve
this using WIX?
Any help appreciated. Thanks in advance.
Thanks,
Sujitha
