[Crm-sig] CRMarcheo -embedding

Dear Christian-Emil, Achille,

When talking about embeddings, I am not so much thinking of an isolated 
item, but things like the Talheim Death Pit with thousands of bones, 
where each exact position is vital for the assignment to complete corpses.

I am also thinking of a thing embedded by multiple layers. First the 
lower half, then the upper half. Should somehow be consistent with the 
physical relations. The first would provide the chronology when the 
deposition started.

We can think of sets of Amphorae, upright metal objects or so, tall 
enough to be embedded by multiple layers.

This would justify embedding in A8, and A3 interfaces taking part in the 
embedding, just as considering intersections of A3 Interfaces as 
physical relations.
