necessarily *that* much 'prettier'. XML is quite a complicated format if
want a 100% compliant reader (do we have a 100% compliant XML parser
written in LiveCode?) - hence why, in this case, it would probably be
to have a wrapper around a well established XML library in LCB.
Why reinvent a wheel which many other people have already decided needs
(Although, having said that, there is something quite pleasing about
