I did not put XML on the Reservation Codes lists as there has been a lot of confusion here over its use in the past. It sometimes brings up a Leisure Links rate that requires an ID (though in the past I don't remember any posts stating that a hotel ever actually asked for one.)
I have no problem putting it in the Reservation Codes list. But remember that the current list is a pairing down of TrojanHorse's original list. I will PM Bruce to see if he thinks there would be any issues and assuming there are none, I will put back in the list.
BTW, using the new search engine, will quickly and easily bring up the past threads discussing the XML code (including some posts where others have stated they have used the XML code outside of the US, Munich in particular, with no issues.)
