In JavaScriptCore/icu and WebKit/icu, the ICU library headers are included, with the only copyright notice being: Copyright (C) 1999-2004, International Business Machines Corporation and others. All Rights Reserved. Which is surely not enough. You'd need to include the ICU license, which terms are the following: Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, provided that the above copyright notice(s) and this permission notice appear in all copies of the Software and that both the above copyright notice(s) and this permission notice appear in supporting documentation.

WebKit doesn't include ICU - it relies on the library being provided by the OS (as is the case on Mac OS X), or by an embedding application (Safari 3 on Windows). I'm not sure if the "appear in all copies of the Software" clause applies in this case - maybe this needs to be brought to Apple lawyers for consideration.
It includes ICU *headers*, look for yourself in JavaScriptCore/icu and WebKit/icu. See the README there as to why.
Sure, we could include the license. I don't think there's likely to be any practical problem here, but it's a lot easier to add a file named LICENSE than to debate the point.
