Syntax Data Maintenance Requests (Syntax DMRs) serve as the means to apply enhancements to ISO 9735 (Electronic data interchange for administration, commerce and transport (EDIFACT) — Application level syntax rules).
These Syntax DMRs fall into three categories:
DMRs proposing changes and/or additions which are against ISO 9735/V.3 and/or ISO 9735/V.4 related to codes for data elements beginning with '0'.
DMRs against ISO 9735/V.4 which are related to segments beginning with 'U'; composite data elements beginning with 'S'; data elements beginning with '0'. Service directory DMRs against ISO 9735/V.3 are no longer applicable.
DMRs proposing changes or enhancements to any of the syntax rules and associated text specified in the latest release of ISO 9735/V.4 (which includes the service messages AUTACK, CONTRL and KEYMAN).
Syntax rule DMRs against ISO 9735/V.3 are no longer applicable.
Service code DMRs shall be directly submitted to the ISO/TC 154/JWG 1 (JSWG)  using the web form specifically designed for this purpose.
The form can be accessed through the JWG 1 web site: ISO/TC 154 JWG 1 Website.
In addition Service code DMRs can be submitted:
via the UN/ECE CEFACT secretariat,
automatically (as result of new directory [d/e 0054] and/or message type addition [d/e 0065] of which the information has to be provided by the UN/ECE secretariat to the JWG 1 secretariat one month before the scheduled release of the UN/EDIFACT directory set.
Service directory DMRs and Syntax rule DMRs shall be directly submitted to the JWG 1 secretariat.
Service directory DMRs and Syntax rule DMRs shall be forwarded to the JWG 1 secretariat either:
in electronic form as e-mail text; or
as an attachment to an e-mail in MS Word or RTF format, and be addressed to: firstname.lastname@example.org
Those without an e-mail capability should send their Syntax DMRs by fax or letter to the JWG 1 secretariat at:

Syntax DMRs as submitted to the JWG 1 secretariat will be allocated a JWG 1 log number which will be communicated back to the submittor as a confirmation of receipt of the DMR.
For Service code DMRs submitted via the JWG 1 web site, these will be allocated a JWG 1 log number and acknowledged automatically.
Service directory DMRs and Syntax rule DMRs shall be circulated by the JWG 1 secretariat to the experts of JWG 1.
The function of the review shall be to approve the DMR (minor change) or to become a Work Item to be processed by JWG 1. If a DMR is rejected, the reason for the rejection shall be given. Whatever the outcome of the review, the party that submitted the DMR to the JWG 1 shall be notified by the JWG 1 secretariat of the result, including where necessary the reason for a rejection.
DMRs approved as Work Items for JWG 1 shall be processed according to the approved JWG 1 procedures for the progression of its Work Items as set out in the attached Annex.
Approved Service code DMRs shall be applied to the appropriate Service Code List Directories (ISO 9735/V.4 and/or ISO 9735/V.3) and made available as a new directory release at the JWG 1 web site with the same frequency as that applied to the user UN/EDIFACT Directories (currently two releases per year).
The JWG 1 secretariat shall provide the Service Code Publication Team , one month before the next scheduled UN/EDIFACT directory, with all approved Service code DMRs.
These DMRs shall be applied to the appropriate Service Code List Directories (ISO 9735/V.4 and/or ISO 9735/V.3) and made available as a new directory release at the JWG 1 web site at the date provided by the JWG 1 secretariat. To ensure proper publication alignment with the UN/EDIFACT Directory set the web host provider, currently GEFEG, will be informed by the JWG 1 secretariat when to make the new web content available to the Public.
