**Explanatory Text**

Directives are used to describe some metadata or behavioral change on the
definition they apply to. When more than one directive of the same name is used,
the expected metadata or behavior becomes ambiguous, therefore only one of each
directive is allowed per location.
GraphQL allows directives that are defined as `repeatable` to be used
more than once on the definition they apply to, possibly with different arguments.
In contrast, if a directive is not `repeatable`, then only one occurence of it
is allowed per location.

For example, the following document will not pass validation because `@skip` has
been used twice for the same field:
