Comment 2 for bug 1376277

Can you explain you use case a bit more?

Do you need it for something like this:

<Connection>
  <ConfigKey>[Master],num_decks</ConfigKey>
  <Transform>
    <lessthan>4</lessthan>
  </Transform>
  <BindProperty>visible</BindProperty>
</Connection>

The same could be achieved by

<Connection>
  <ConfigKey>[Master],num_decks</ConfigKey>
  <Transform>
    <Invert/>
    <Add>4</Add>
  </Transform>
  <BindProperty>visible</BindProperty>
</Connection>

if we change the property conversion
to
if (value > 0 ) {
    visible = true;
}
