8 Conformance Testing
Table 2 provides the Conformance Testing Method for the MAS Spatial Attitude Generation (CAV‑MSA) 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 the MAS Spatial Attitude Generation (CAV‑MSA) AIM
| Receives | Spatial Data | Shall validate against Spatial Data schema. |
| Produces | Spatial Attitude | Shall validate against Spatial Attitude schema. |
