 | parent_id                   | Element Hierarchy (Parent ID)                            | `parent_id` may be used to infer where an element resides within the overall hierarchy of a document. For instance, a `NarrativeText` element may have a `Title` element as a parent (a "sub-title"), which in turn may have another `Title` element as its parent (a "title).                                                                          |

Hierarchies enable more robust chunking configurations.                                                                      |

 | category_depth              | Element Depth relative to                                | Category depth is the depth of an element relative to other elements of the same category. It's set by a document partitioner and enables the hierarchy post-processor to compute more accurate hierarchies.                                                                                |
