Your note wording is:

"The use of the terms presentation processor (transformation processor) do
not imply conformance to the DFXP Transformation Profile (DFXP
Transformation Profile) specified in [TTML1]. In other words, it is not
considered an error for a presentation processor (transformation
processor) to conform to a profile defined in this specification without
also conforming to the DFXP Transformation Profile (DFXP Transformation

I suggest adding "within this document" before "do not imply" to make
clear that this note is not a gloss on TTML 1 SE but is a clarification of

Also there's a typo in the last sentence - I think you means "DFXP
Presentation Profile (DFXP Transformation Profile)."

Other than that, looks good to me (and less wordy than my proposal),
