We aren't the only ones using the particular disk. It's also for a couple of Deville & Seville years, and the first 3 years of the original SRX. Just a few more owners Cadillac has chosen to flip off.
No success yet trying to make a hybrid disk by adding maps from a different disk. However, a couple of interesting things have been identified. By stripping out the index files for other regions, I can rebuild the 2007 cadillac disk as a small enough image to fit on a single-layer dvd, and found that burning a DVD+R of that image works in the XLR. In fact, a DVD+RW seems to work fine too, thereby reducing the testing cost significantly. And, since these work fine, there appears to nothing critical hidden away on the original disk.
The big map file (alldata.kwi) on both the 2007 xlr disk and a 2008 toyota gen4 disk identify themselves as format version kiwi01-22-00, so that's promising. The XLR's denso unit is almost certainly generation 4 then, as the disk for my 2007 lexus's gen5 system is quite different.
If anyone has a 2008 or 2009 disk, I'l love to know the contents of the spec.kwi file (which is a very small text file on both the disks I'm looking at).
