What is the meaning of "Windows [versions]: this value is not available." statement in MSDN?

When reading the MSDN documentation for WinLocalLogonSid value of WELL_KNOWN_SID_TYPE enumeration, that is:

WinLocalLogonSid

Indicates a SID that matches a local logon group.

Windows Server 2008 R2, Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003, and Windows XP:  This value is not available.

there is an uncertainty of meaning in the system requirement statement. It can be one of the following meanings:

  1. WinLocalLogonSid start to exist in Windows 8.
  2. In case of the documentation is not yet updated to Windows 8, it can also means that WinLocalLogonSid only exists in Windows versions prior to Windows XP.

Unfortunately, those enumeration values were not documented in the header source code.

I made a check for WinNT.h from Windows 7 SDK, surprisingly, the WinLocalLogonSid was available there. I don't have a definite conclusion for this fact because there is a possibility that an identifier is declared but not yet implemented.

So, could someone experienced on this stuffs tell me what is the meaning of such a system requirement statement in MSDN?

Notice that it says at the bottom:

Minimum supported client: Windows XP

Minimum supported server: Windows Server 2003

So yes, it is only Windows 8.
