I haven't tested it, but try to go to Xcode preferences and under File types set the extenral editor for File -> text -> text.xml to TextMate. Of course then all XML will probably open in TextMate.
This does indeed work, but as you noted, every xml file opens in TextMate.
http://lists.apple.com/archives/xcode-users/2004/Feb/msg00439.html has some information on how to customize Xcode's file types list
Great! Thanks, this is what I was hunting for. A way to specifically define .tmproj files.
