This little 'or' probably isn't necessary, since they'd both be default
constructed, right? So they'd be equal if both missing?
Also, std::tie trick would probably work here then.
That is:
`std::tie(lhs.DefaultSeverity, lhs.Class,...) == std::tie(rhs.DefaultSeverity,
rhs.Class, ...)`
You can even create a private method of 'get-tied-version' so you could only
type it 1x.
