The children type says how a block lays out its children. In Hypermedia a list belongs to the parent block. A block's childrenType attribute sets how its children render: Group (plain, the default when the key is absent or null), Ordered (a numbered list), Unordered (bullets), Blockquote, or Grid (columns, with the parent's columnCount). Document metadata carries the same key for the root-level blocks, and a Slot block gives a top-level list a parent when one is needed. See Blocks.
