# <extern>

Element: extern

Child Elements: none

Description: Identifies an external grammar by name so that the entities contained by the grammar do not have to explicitly name the grammar. For example, if another grammar is `grammar1` and an entity within it is `entity1`, then in the current grammar, the entity can be referred to as simply `entity1` rather than `grammar1/entity1`.

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