Yes.

Among other things, SCSI is very peculiar in that it sends out many "draft" standards but allows devices to be built that "conform" to those drafts.  Contrast that with the much better IETF practice, where drafts are intended only for standards development, and "conforms" is a term that can only be used with official standards (RFCs).
