So what's the skinny on using XML?

It's listed as a leisure rate, but not attached to any company per se. A reply to a post of mine and some PM's suggest that this is an ID required type rate code.

I've been using it left and right in the US without ever being questioned but I'm planning to use it for a trip to Munich in the late winter/early spring. The last thing I need is to get over there and find out they're going to jack the rate 2.5x on me because I don't have an ID of some sort.
