-To reduce excessive nesting, a parameter inside a collection's `options` parameter sits at the same level of nesting as the containing collection in the `nodeView` section.

+> **Note**: In case of deep nesting, i.e. a child of a child of a `collection` and `fixedCollection` parameter, the deeply nested child in principle should be translatable at the same level of nesting as the `collection` and `fixedCollection` parameter, but this has not been fully tested for this first release.

 #### Reusable dynamic text
 
 Also, the base text file may contain the special key `reusableDynamicText`, allowing for a node parameter to be translated once and reused elsewhere in other node parameter translations.
