So, the question here is > more why supporting a feature that no one should use anymore... the point is: The program I have shown is valid in both modes. One version is obviously stupid (referring to the constant 'xml' and not doing anything further) but still valid. Being just a developer from down the street I might not have been aware of that and delivered the program to a user who, for whatever reason, had short tags enabled and probably won't see a proper error. If they know there are workarounds ( <?='<?xml ?>'?>  is a portable version) but such things are a real pain. Having langage changing based on an ini setting is bad. (ze1 compatibility mode was really really fun in early PHP 5 ... not) johannes
