What is failing, does it not work or does it not start?  Like I say, I don’t have the syntax swapped in right now, but off the top of my head

Looks dodgy.  I would have expected to see

<Rule xsi:type="NOT"/>
  <Rule  xsi:type="Something" attributeValue="working" attributeName="some_attribute" />
</Rule>
