* in (usually a field suffix after the human-readable name
|

* form element).
|

* - label: The label to show for the machine name preview.

* - replace_pattern: A regular expression (without modifiers) matching
|

* disallowed characters in the machine name; e.g., '[^a-z0-9]+'.
|

* - replace: A character to replace disallowed characters with; e.g.,

* '_' or '-'.
|

* - standalone: Whether the preview should stay in its own element
|

* rather than the suffix of the source element.
|

* - field_prefix: The #field_prefix of the form element.
|

* - field_suffix: The #field_suffix of the form element.
