 Requires a minimum of two arguments, which are unique value generation rules defined using expressions. The function evaluates each rule and then checks the value generated for uniqueness in the target app/directory. The first unique value found will be the one returned. If all of the values already exist in the target, the entry will get escrowed and the reason gets logged in the audit logs. There is no upper bound to the number of arguments that can be provided.
