Thanks Albert, yes, you're right.

The relationship is: Segmented array (1) <---> (N) buffer (1) <---> (M) element. So element is an item, e.g. an offset, a pointer, ...

I'm not sure if I understand your point correctly, can I assume you mean: Segmented array (1) <---> (N) slot (1) <---> (M) element ?
