Segment: As I think more of it, this seems just like versioned content
with a known end (length), with continuous numbering from 0...length-1.
Whereas "usual" versioned content has an open end, but a latest version
(somewhere). (Of course, the difference is that versioned content is
similar or related content in a sequence, whereas segments are parts of
the whole data.)

Empty value: I would not allow this special case. You will soon find
someone who tries to have an empty component, but for that needs to have
some other (dummy) key just after that. Better to either allow empty
components in general, or don't allow them here eiter.
