8 Conformance Testing
Table 2 provides the Conformance Testing Method for the CAE-AST AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present and conform with the Qualifier, if present.
Table 2 – Conformance Testing Method for CAE-AST AIM
| Receives | Enhanced Audio Object (Transform) | Shall validate against Audio Object schema. Audio Data shall conform with Audio Qualifier. |
| Produces | Enhanced Audio Object | Shall validate against Audio Object schema. Audio Data shall conform with Audio Qualifier. |
