Versioned (interface)

Version and valueVersion are actually the same. Users that don’t care about the distinction between container and value versions can simply use ‘version’.

The usage of containerVersion is optional, and its interpretation is implementation dependant. In general, it implies changes that are more fundamental than value changes, such as structural changes.

For example, an Image that changes its size or pixel type can be a container change, while pixel data changes are value changes.
