aura:interface

Interfaces determine a component’s shape by defining its attributes. Implement an interface to allow a component to be used in different contexts, such as on a record page or in Lightning App Builder.

The aura:interface tag has the following optional attributes.

Attribute	Type	Description
`access`	String	Indicates whether the interface can be extended or used outside of its own namespace. Possible values are `public` (default), and `global`.
`description`	String	A description of the interface.
`extends`	Component	The comma-separated list of interfaces to be extended. For example, `extends="namespace:intfB"`.
