I can live with that. ;) I remember reading some time ago about how SCSI specifications get borrowed from on occasion in the creation of other specifications/standards. A quick google search produces: http://www-128.ibm.com/developerworks/power/library/pa-spec8.html : which I am pretty sure was the same thing I read before.
