Technically, this isn't an XML issue so it should be under a different forum.
That said, while it is feasible to create an addon that would unequip an item, it's an awful lot of work for something that can be done just by opening the character panel and dragging the shield to inventory. The other issue is that using a plugin for it at this point in time would potentially open the door to the "crash to desktop" inventory bug since you'd have to use the Backpack:PerformItemDrop() method which would mean accessing the Backpack item which is what seems to be causing many of those nasty crashes. I know that I won't be putting any time into backpack related plugins until Turbine fixes that crash bug - the out-of-synch bug was annoying, but crashing the client is unacceptable for me
