Re: Tool info specification (Re: action-221 summary of overriding discussion)

Orthogonal usually means that one issue intersects with another but is not otherwise determined by it. The term comes from the idea of a two-axis system in which the axes are at right angles (orthogonal).

So they are not unrelated—their combination may be extremely important—but they can vary independently and the value of one does not entail any particular value for the other.

Orthogonal is different from parallel, where there is a correspondence of value, and also from totally independent, where there is no meaningful intersection or relationship between two things. 

Hope that help explain the academic mumbo-jumbo

E.g. there might be no disambiguation or mt-confidence annotation at all. The "toolInfo" data category allows applications to interrelate the annotations, if they are available - but we don't require testing that and don't create new conformance claims. That's a huge benefit IMO.
