I'm sure the relevant authorities are aware of the problem, but the XML User Nodes Generator ticker appears to be broken.

Specifically, ampersands (i.e. &) are no longer being escaped. This means that if you have a node entitled "foo & bar", it is not rendered as "foo & bar". Thus a parser such as XML::Simple coughs and dies when it encounters it.

Do not adjust your set, this is entirely normal.

print@_{sort keys %_},$/if%_=split//,'= & *a?b:e\f/h^h!j+n,o@o;r$s-t%t#u'
