No custom scalar URLs in GraphQL schema fragment

[eugaia]

This isn’t really a big deal, but since I’m reading through the latest GraphQL specs, I noticed that on this page of the specs it says:

When defining a custom scalar, GraphQL services should provide a scalar specification URL via the @specifiedBy directive or the specifiedByURL introspection field.

And I noticed that in the GraphQL schema fragment there’s no @specifiedBy directive set for the scalar types Int64 and DateTime.

While it’s not a requirement for GraphQL compliance, you may want to add that directive with an appropriate URL so that you’re following the recommendation of the specs.
