Usage notes
- Use this API in the document creation workflow before the affected page, resource, field or catalogue object is finalised
- Keep object, field and resource names, and returned handles, stable whilst the document is being finalised
- Loaded-document object references may be indirect; resolve arrays, dictionaries, or streams before inspecting nested values
