Responses and scoring

The controller defines scoring for this element. Browser scoring returns one outcome per element. Your application combines those outcomes into an item score and handles trusted server scoring.

Model, configuration and session reference

The model holds content, configuration controls the editor, and the session holds the response. Fields below come from generated JSON Schemas.

Schema version: @pie-element/math-inline@13.0.6. Example version: 13.0.4. Use the schema matching your content. Schema checks cover data structure; controller validation checks authoring rules.

SignLanguageCardPayload

Field	Type	Meaning	Default / values
`signLang`	`string`	Language tag for the signed translation — BCP 47, which admits ISO 639-3 subtags for languages with no 639-1/2 code. "ase" is ASL, matching QTI 3 `xml:lang`. This is the language of the adaptation, not the item's base content language (AfA/PNP's `languageOfAdaptation`). The distinction is load bearing: a Spanish item's signed alternate is LSM, not ASL, so `signLang` must never be inferred from the item or assessment content language. Optional, and redundant on almost every card. The card's `language` states the same code and is the only field pie-players resolves a card on — resolution runs before anything knows the card is a signing card, so it can only key on the generic field — and the player falls back to it when this is absent. Author it only where the two differ: a card tagged with the item's content language (`language: 'en-US'`, `signLang: 'ase'`) so resolution reaches it by the default-language rung. The pie-api-aws importer emits `language` alone.	`—`
