xmind_add_boundary

Add boundaries to a mindmap. rangeType 'parent' wraps the whole topic; 'children' groups a contiguous range of the topic's attached children (0-based rangeStart..rangeEnd inclusive). The topic is identified by the id in its <!--t:id--> anchor. An optional title labels the boundary — use it to give a run of siblings a collective name ("MVP scope") or a status tag ("done" / "TBD"); omit it for a pure visual highlight. Put every boundary you are adding in one call via items (up to 200) — do NOT call this once per boundary. An item with bad arguments is skipped and reported; the rest are still written.
