8 Conformance Testing
Table 2 provides the Conformance Testing Method for Audio Object Rendering (CAE-AOR).
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 Audio Object Rendering (CAE-AOR) AIM
| Receives | User Command | Shall validate against User Command schema. |
| Audio Scene Descriptors | Shall validate against Audio Scene Descriptors schema. | |
| Produces | Audio Object | Shall validate against Audit schema. |
| Shall validate against Licence Confirm schema. |
