Exif gets promoted to an IFD and there is nothing criminal because this directory shoudn't be visible in a common way. Offset to this directory will not be placed anywhere except the ExifTag. And any "good" reader will just skip unknown tag, as specified by Tiff standart. The problem is how to write such subdirectory using another offset tag (not subifd tag provided by TiffLib). But in any way, thanks for your letter, it is rather pleasant to get answer so quick.
