/**
 * INTERNAL:
 * Either create a new change record or update with the new value.  This is used
 * by attribute change tracking.
 * Specifically in a collection mapping this will be called when the customer
 * Set a new collection.  In this case we will need to mark the change record
 * with the new and the old versions of the collection.
 * And mark the ObjectChangeSet with the attribute name then when the changes are calculated
 * force a compare on the collections to determine changes.
