Hi Ben,

Validation scripts don't currently have a way to skip a particular row without rejecting the whole set of rows. Doing an update that doesn't actually change any values shouldn't be a problem, though it would insert audit records for datasets and lists.

There's also the problem that some of these rows would be updates and some would be inserts. In the future, we hope to support a merge-style option as well, which would address this case, but for now the client would need to know which to do, and at that point it's probably just as easy to figure out if anything's changed for that row.

Thanks,
Josh
