I have been trying to come up with a solution to place a constraint on a Select1 field within a repeat. The constraint requires that no two Select1's have the same value. If two of the Select1's have the same value, these two Select1's become invalid.
I have been investigating how to go about doing this and the problem I see if if you compare the nodes, you have to also not compare the same node against itself. Is there a way to iterate through all of the other nodes and compare then against yourself within the constraint property within a bind using XPath 2.0?
Is this constraint even achievable at all?
This is an unlimited repeat and the Select1 initially has no value and is invalid
