[oXygen-user] Xalan-J 2.6

Howdy all. I'm interested in some of the newer parts of EXSLT. These appear to be supported in Xalan-J 2.6 but Oxygen 4 ships with 2.5.x. Thus: 1) Are there plans to upgrade to 2.6 during the maintenance cycle of Oxygen 4? 2) If not, can I just drop in Xalan-J 2.6, or is there some other way to get newer exslt support? --Paul
