Values are listed only where real documents use a small, closed set; the number after each is how many documents use it. “Seen in” is the share of documents containing IndexOptions that set the attribute.
Counts come from a survey of 305 IDML documents (2026-10-11); only aggregate facts are published. Paged’s support is read from its importer and exporter source, and the typed properties from the engine catalog.
