This would be great and it's how I always assumed GPX worked, but
since joining this list I've found it doesn't work. Because there is
no mechanism for performing some of the arrows like

a proposed GPX extension->a holy GPX extension

because nobody (here in this list or elsewhere) cares, or perhaps even
knows how to make it happen even if they do care. So if your
progression is to work, part of the 'rescue' job is to work out how to
trigger and effect each of the arrows.

Simon.
