[Jiewen] Agree. Will add in V3.
> 2. Can we group all the macros at the top followed by structure definitions?
[Jiewen] I believe we had better to keep macro close to the data structure definition.
Take UefiSpec.h as example.
EFI_MEMORY_xxx is close to EFI_MEMORY_DESCRIPTOR
EVT_xxx is close to EFI_EVENT_NOTIFY
TPL_xxx is close to EFI_RAISE_TPL
Same example in Acpi.h
We put definition close to the structure, instead of put all definition together on the top.

[Jiewen] Agree. Will add in V3.
> 4. I see line 80 is commented out. Can we remove that line?
[Jiewen] This is a typical way to define a variable length field.
You may find similar examples in EDKII. Just search [];
C:\home\edkii\edk2\MdePkg\Include\Guid\CapsuleReport.h(84): /// CHAR16 CapsuleFileName[];

C:\home\edkii\edk2\MdePkg\Include\Guid\WinCertificate.h(116): /// UINT8 Signature[];
> 5. Please add some description about the change after line 5.
[Jiewen] Line 5 ? It is about license.
Would you please clarify what description is required there?
