Enum owoof::projection::Concept

pub enum Concept<'a, V> {
    Location(Location),
    Entity(&'a EntityId),
    Attribute(&'a AttributeName<'a>),
    Value(Affinity, &'a V),
}

Honestly, I don't even know what this is about. The V type typically implements HasAffinity so we could just about discriminate on Affinity::Entity and Affinity::Attribute instead?

I'm almost certain this pre-dates that trait and the crate::Value type though so maybe the hope was I could just use this instead of having those and keep things simpler?
