Usage notes
- Use this API in the Tagged PDF accessibility 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
- Keep begin and end calls balanced, provide alternate text for non-text content, and attach MCID values to the right page content
