Hi Brandon, Thanks for the info. I think the spec is out of date, I will propose to update the spec and file a document change bug on Bugzilla system.

If the path starts with a "$" character, then one of the system environment variables, $(WORKSPACE), $(EDK_SOURCE), $(EFI_SOURCE), or $(ECP_SOURCE) is being used; only these system environment variables are permitted to start the path of the included file. Yet from experimentation, all macros defined in DSC files seem to be permitted in !include statements by the build tools. Is the spec out of date, or is the code wrong? I think the code in question is _GetMacros() in BaseTools/Source/Python/Workspace/WorkspaceDatabase.py<https://github.com/tianocore/edk2/commit/0d2711a69397d2971079121df4326d84736c181e#diff-7cfd5e9099421b207e7718d47950d40dR148> (https://github.com/tianocore/edk2/commit/0d2711a69397d2971079121df4326d84736c181e#diff-7cfd5e9099421b207e7718d47950d40dR148).
