UpdateDifferentValues

The existing document will be updated based on the document being inserted. If there is a pre-existing document in the local store with the same ID, compare its value to the current value of the document. Update any differing register and attachment leaf values in the document to match the given value. Nothing is removed. This is equivalent to using an if statement to check each value in the provided payload against the local document value.

Warning: In cases of concurrent writes, non-differing values will be overridden by peers because this write strategy excludes values from the given payload that are identical to those in the local store.
