TDL Change Requests

Change Requests (CRs) for any part of the TDL Standards are managed by a TDL development and maintenance team which is part of ETSI's MTS technical committee (TC-MTS). The following rules and instructions shall be followed:

  • TDL CRs shall only be reported via ETSI's Bug Tracker (Mantis) under the sub-projects corresponding to the different TDL parts.
  • A CR shall include a description of the related use case and it may propose a concrete solution (example: original text + revision marks) in the attachment. If the solution is inadequate, the reporter will be requested to provide a refined one. If no solution is forthcoming, the CR may be rejected.
  • The maintenance group may propose alternative solutions. These will be discussed publicly via Mantis with the reporter.
  • The TDL mailing list may be a forum for discussion of CRs and other technical comments but final resolution of all CRs will be the combined responsibility of maintenance group and TC-MTS.
  • Wherever possible CRs will be resolved by maintenance group, with the agreement of the reporter. Final arbitration rests with TC-MTS.
  • Please make sure to select the relevant sub-project first before reporting issues!

Anyone can track the status of any reported CR on any part of the standard after signing up for an account. Please note that standard maintenance work is not a full-time activity. You will receive responses within a reasonable time-frame, but probably not immediately.

CRs for the TDL web site itself are managed by the This email address is being protected from spambots. You need JavaScript enabled to view it.. These CRs can be reported directly to the TPT.
