Whoever did this in 'may-ignore' stuff in the first place must have skipped communications 101. Firstly, if it may be ignored, then why send it in the first place? Secondly, any part of anything *may* be ignored, but it is up to the receiver to make that decision. When you get told by the communicator to ignore this and not that, you tend to think about just ignoring the whole jolly lot... because the message becomes to conveluted, confusing and too much effort to understand. > My original post had no responses but I'm not sure if that was because > no-one is really all that bothered about this subject (for us it has some > potential in our versioning strategy) ? Go back and check the setting of the <may_be_ignored_flag = 0> Regards David
