[CONNECT U7 C++] Rerference File Attachments

In V8i I was able to specify a reference file attachment method by:

			ReferenceFile		*pRefFile=mdlRefFile_getInfo( attachedModelRefP );
			if ( pRefFile )
			{
				pRefFile->display.fb_opts.attachMethod = ATTACHMETHOD_CoincidentWorld;
                ...
            }

but I don't see ATTACHMETHOD_CoincidentWorld nor do I see anything like display.fb_opts.attachMethod in a CONNECT DgnAttachmentP struct.
