- Given a current property and a new property, this function returns the

-
- node1 {

- node1 {

- He we want to use an int array for 'value'. The first property
- suggests that a single int is enough, but the second one shows that
- it is not. Calling this function with these two propertes would
- update the current property to be like the second, since it is less
