Technically, the STF execution process does not inherently produce auxiliary outputs beyond the success or failure result. In this context, we propose an extension to include additional information that may be beneficial for implementors or useful for executing other subsystems reliant on values generated post-STF execution.
When the error or success values are not pertinent to your test vector processing procedures, you may disregard them as necessary.
A mapping of error code semantics is provided within the ASN.1 schema for each specific subsystem.
