Is it possible that validation functions returns complete location?

Not only start of the line and column but also end of the line and column?

@saihaj @IvanGoncharov what do you think?

If an error can be associated to a particular point in the requested GraphQL document, it should contain an entry with the key locations with a list of locations, where each location is a map with the keys line and column, both positive numbers starting from 1 which describe the beginning of an associated syntax element.

So as per spec we only return starting position. But I can see how it is useful probably graphiql has something for error recovery purposes. I suppose we can file this against spec first?
