# <extern>

Element: extern

Child Elements: none

Description: Identifies an external grammar by name so that you do not have to explicitly name the grammar when you refer to the entities that it contains. For example, if the external grammar is called `grammar1`, and it has an entity `entity1`, then in your current grammar, you can refer to the entity as `entity1` rather than `grammar1/entity1`.

Example: `<extern name="grammar2"/>`

Attribute | Value | Default | Description
--- | --- | --- | ---
`name` | <grammar name> |  | The name of the external grammar. A value is required.
