And you can certainly do that for EME. Whether you can independently
implement a CDM that supports a specific key/encryption system is another
matter. You may be required to obtain a license to be able to implement and
deploy some systems, and that license may impose restrictions
(encumbrances) on the form in which the CDM is distributed or integrated
into a larger system. This is an orthogonal matter to independent
implementability.

I am simply attempting to explain that the concept of independent
implementability includes both encumbered and unencumbered implementations.
You have chosen to restrict your interpretation to the latter. So, if you
are open to a suggestion, then may I offer the more specific phrase
"unencumbered, independent implementation" as a better expression your
intent?
