another issue. <bind nodeset="/data/string1" constraint=". != ''" type="string"/> doesn't seem to work as a constraint. i understand i could use required=true(), but any reason why this doesn't work?

    So I have 2 nodes that need to be both visible at the same time but collectively only one of them must be required. Neither of them can be have required= true(). I essentially need the constraint field to allow me to use .!="" or similar. Thoughts?
