tables are to be maintained. It also documents the processes used for receiving and processing change requests. A change request form is provided, and there is a second form for collecting information about proposed additions. Any party can submit change requests. When submitted, requests are initially reviewed by the registration authority for completeness. When a fully documented request is received, it is added to a published Change Request Index. Also, announcements are sent to the general LINGUIST discussion list at Linguist List and other lists the registration authority may consider relevant, inviting public review and input on the requested change. Any list owner or individual is able to request notifications of change requests for particular regions or language families. Comments that are received are published for other parties to review. Based on consensus in comments received, a change request may be withdrawn or promoted to "candidate status". Three months prior to the end of an annual review cycle (typically in September), an announcement is set to the LINGUIST discussion list and other lists regarding Candidate Status Change Requests. All requests remain open for review and comment through the end of the annual review cycle. Decisions are announced at the end of the annual review cycle (typically in January). At that time, requests may be adopted in whole or in part, amended and carried forward into the next review cycle, or rejected. Rejections often include suggestions on how to modify proposals for resubmission. A public archive of every change request is maintained along with the decisions taken and the rationale for the decisions. Criticism Linguists Morey, Post and Friedman raise various criticisms of ISO 639, and in particular ISO 639-3: The three-letter codes themselves are problematic, because while officially arbitrary technical labels, they are often derived from mnemonic abbreviations for language names, some of which are pejorative. For example, Yemsa was assigned the code jnj, from pejorative "Janejero". These codes may thus be considered offensive by native speakers. However, codes can be changed with a request submission on SIL's website. The administration of the standard is problematic because SIL is a missionary organization with inadequate transparency and accountability. Decisions as to what deserves to be encoded as a language are made internally. While outside input may or may not be welcomed, the decisions themselves are opaque, and many linguists have given up trying to improve the standard. Permanent identification of a
