Decision-tree references
- OMG DMN 1.5 — latest formal prior art for decision requirements, decision logic, and FEEL; not a native diagram.zip renderer.
- Mermaid flowchart syntax — supported renderer for readable informal decision trees.
- ISO 5807:1985 — flowchart symbol convention relevant to decision/process notation.
DMN support would require XML parsing, decision requirements notation, and likely FEEL-aware validation. Do not imply that a Mermaid diamond is DMN-conformant.
