Ignore this post. I figured it out. I was using a complex name for my XML files (with a date code and build name). When i copied them to the system, i renamed them. When i renamed them, the system tagged a .xml to the end so i ended up with a double extension (sysprep.xml.xml). Yesterday when i was banging my head on this thing, i swear i was able to open the file with notepad directly. I guess i must have browsed to it. And since 2008 was hiding the extension of system files it looked normal to me to see it in explorer that way. Ah well... These aren't the droids you're looking for, move along...
