Proposed by Martin Perlot, RV-C Administrator.
To Section 7.3 Standard SPNs, add
Standard SPNs must be encoded as non-instanced failures, per section 3.2.5.6. In each case, the MSB is zero, and the ISB and LSB contain the SPN value (see Table 3.2.5.5).
Justification: This is frankly not obvious from the current text.
