Antoine Pitrou updated ARROW-6507:
----------------------------------
Description:
>From discussing ARROW-6506, [~bkietz] said: an extension type might place more
>constraints on an array than those implicit in its storage type, and users
>will probably expect to be able to plug those into {{Validate}}.
So we could have a {{ExtensionType::ValidateArray}} (resp.
{{ValidateArrayFull}}) that the visitor for {{ExtensionArray}} can call,
similarly like there is also an {{ExtensionType::ExtensionEquals}} that the
visitor calls when extension types are checked for equality.
