Hi All, Related to this is the question of versioning. Say the version of TML on the CE changes, how many prior versions should the CE support to be able to provide service to FEs that haven't upgraded yet? [This also calls for "Unsupported Media" and "Unsupported Version" exception handling and error reporting capability.] Regards, Alex. www.garlandsoftworx.com -----Original Message----- From: [email protected] To: [email protected] Sent: Tue, 3 Oct 2006 10:34 AM Subject: Re: Hybrid TMLs This is one of the reasons why there needs to be a mandatory to implement TML. I am inclined to observe that Given the existence of at least one common TML, it is permitted for the CE to simply use a TML that is common across all FEs. A CE which has support for multiple TMLs, and which can manage the selection and management issues of using such (including, if used, multicast) is free to choose to use multiple TMLs to speak to different FEs in the NE. I.e. a single TML works, but we have no reason to prohibit multiple TMLs, if someone builds a CE that can do it.
