Comment(by s_ochsenknecht):

 Ok, another proposal would be to store an empty value for string type
 values (also for collection of strings) and throwing a validation error
 for e.g. integer types: "invalid option value ''"

 This is probably better than storing a default constructed value, which
 could be undefined. Or in other words, what is an empty integer? undefined
 or invalid (I would prefer invalid -> exception)?

 Please comment.
