# Include

The `<Include>` element includes operations defined elsewhere in the field standardization dictionary.

An included fragment of XML behaves as though the XML was inserted at the location of the `<Include>` element, except that any variables defined or modified by included operations revert to their previous state when the included operations finish.

Attribute | Description
--- | ---
`id` | The `id` of an Includable element that contains the operations to include.

The following example defines an AddField operation that is used in multiple places:

    <FieldStandardization>
        <Includable id="inc" source="include-only">
            <AddField name="myField" value="fieldValue" />
        </Includable>
        <Include id="inc" />
        <Field name="parentField">
            <Include id="inc" />
        </Field>
    </FieldStandardization>
