If you really need to create lists of value object wouldn't they 
actually be entities?

Usually when I need to display 'value objects' without the relation to 
an object I approach them as being entities. So having a repository 
doesn't harm.
It is possible to simply create a repository for your value objects.

Currently working on an order form with dynamic properties (first 
approached as value objects). Finally my end model looks like:

OrderForm - 1:n - OrderOptions
Order - 1:n - OrderedOptions - 1:1 - OrderOptions

Does coming to a use of both entities (OrderOptions) as well as value 
objects (OrderedOptions).

Hope this helps you!
