I agree that the edge cases make this extremely challenging. That goes both for making the standard contracts and the software that manages them.

For each contract, we go through a multi-month process with 40+ attorneys to vet the standards against all of the permutations they've seen without making the agreements too complex.

On the software side, this is a big part of the value of structured data. We make it easier to keep track of the different variations you've agreed to in different contracts. It's a tricky balance to make sure our users are never constrained from closing new customers while still making sure the software sticks to and takes advantage of the standards.
