Not as strict maybe, but I am sure, you are planning to provide 
(normative or non-normative) guidelines, when and how to use the 
oax:hasContext property. This is the same to me.

Just a way to say that the full meaning of the annotation may not be evident unless it (the target or the body, depending on which part the oax:hasContext is attached) is considered within the context provided by the oax:hasContext part of the graph.

You are loosing me here. In another email you are vouching to name the 
property "hasScope", which is clearly a validity criterion such as in 
"out of scope" == "invalid" .
Also I am not saying that you can infer that two annotations are the 
same. I talked about the Target, i.e. SpecificResource and Selectors. 
Does your idea of context help you to decide whether two targets are the
