The way I see it, is that escaped XML is sure to contain ampersands, but
'real' XML is sure to contain < > brackets. If it doesn't contain any
angle-brackets, then what's XML about it - it contains no tags? ;-)

So I guess that looking for < or > will work as a heuristic, in 99.9999% of
the cases - if not more ;-)

Oh, and yes I agree with the other posters that it would be better to store
it unescaped, and escape it where you need it.
