Given T1 <-- T2 and M encoded with T2
If I have both T1 & T2, I can chose either.
If I don't need the extra data added per T2, I can chose to use T1.
By definition of T1 <-- T2 then a message encoded with T2 *must* be decodable by T1.
If you decode M with T1, then you will "slice" your message somewhat, but that might be something you want, or still better that nothing when you don't have T2.
This would allow senders to "evolve" their templates, giving the choice to receiver to use or not this "evolution"
