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