| Clarify that C data arrays must be byte arrays for PCD value fields; prohibit C format and | |||
| Registry Format GUID structures in VOID* PCD value fields | |||
| Update non-zero number is True, only 0 is consideered False | |||
| Prohibit specifying items as architecturally specific and also common | |||
Changed <RegistryGuid> to <RegistryFormatGUID> in |
|||
| 3.4 | |||
Defined <GuidValue> as a <CFormatGUID> for this release (need to allow registry format in a future release) |
