Enum CaptionParent 

pub enum CaptionParent {
    Body,
    Container,
    ContainerAfter,
    Item,
}

Where a picture’s or table’s caption text item hangs in the docling-JSON tree (#390). docling’s backends do not agree, and the JSON structure is the only surface that shows it (Markdown, DocLang and LaTeX place a caption by its item, whatever its parent): the PDF pipeline parents a layout caption to the picture or table it belongs to, while every declarative backend creates the caption with doc.add_text(label=CAPTION) and no parent — the document body — even when the item itself sits in a group or under a section header (JATS, LaTeX, HTML, Markdown, EPUB, AsciiDoc all do). The office backends hang a chart’s title caption off the chart’s container (the sheet group, the slide, docx’s current parent, docling#4190) — that is Node::Chart’s own path, not this choice. A backend that adds a new captioned item picks the variant matching upstream’s add_text call for that format; the default is upstream’s default.

Variants

Body

#/body, listed after the enclosing top-level item — docling’s add_text default, which every declarative backend leaves alone.

Container

The item’s own container (its parent), listed ahead of the item: the caption is created first, as docling’s office backends do.

ContainerAfter

The item’s own container, listed after the item: docling’s HTML backend adds a <figure>-wrapped table, then its <figcaption> under self.parents[self.level] (docling#4050).

Item

The item itself — the caption is the picture’s or table’s first child, as docling’s PDF pipeline attaches a layout caption.
