I would second that. The correct mapping between O&M and Data Cube is 
not (always) to equate a qb:Observation with an OM_Observation. If the 
use case document were framed around specifically the O&M model there 
would be a danger of that confusion arising.

I have such a use case, which is touched on in ISSUE-32. I could expand 
that.
