It's in the comments on 2.1.d in the draft at

I think it should be bundled, but I don't know the expert opinion on 
that.  I think that would make streaming TPM-d media more expensive
and that's entirely just.

TPM is a whole class of formats.  How is it different to say 
TPM-extended formats from Office-extended formats?   You don't have 
to use the Office extensions, of course, but why should the licence
forbid you from doing so?

Anyway, I'm not asking for support for TPM.  I'm asking for permission 
only when the use is redundant.

Maybe.  I'm not familiar with iPod locking.

Yes, I'd love to make DRM irrelevant.  DRM can be used to pervert many 
things.  It would be nice to at least have the option of getting our own 
back on DRM supporters.
