Hi Everyone,

I am wondering if EDK2 source already supports SUBTYPE_GUID format in FDF.
I tried the following case similar to the EDKII FDF specification but failed.

Specification:
FILE FREEFORM = 85C3EBE1-F58F-4820-8AD3-F2FB62DC3A23 {
FvAlignment = 512K
SECTION SUBTYPE_GUID AFC13561-9A65-4754-9C93-E133B3B8767C = $(WORKSPACE)/MyPackage
/MyNewType/Binary/newform.bin
}

My case under the [FV.FvRecovery] field of EmulatorPkg.fdf:
FILE FREEFORM = 85C3EBE1-F58F-4820-8AD3-F2FB62DC3A23 {
SECTION SUBTYPE_GUID AFC13561-9A65-4754-9C93-E133B3B8767C = EmulatorPkg/MyPicture/Picture.jpg
}
Actually, I removed FvAlignment since it causes the build error too.
