These two changes go together. They are only separated because GitHub won't take a suggestion that applies across a changed line.

I have accepted this change, but made it a complete sentence.

[TallTed]

I do not understand what the actual [=controller=] is supposed to mean, nor what it is suggesting is the ersatz [=controller=].

Suggested change

	[=controller=] of a [=verification method=], the actual [=controller=] can generate
	proofs that satisfy the method.
	[=controller=] of a [=verification method=] can generate
	proofs that satisfy the method.

[David-Chadwick]

The actual controller refers to the actual controller, rather than the asserted controller. Since the assertion can be true or false, if it is true then the asserted controller is the actual controller, if it is false, then the asserted controller is not actually the controller.

[TallTed]

I think I see what you mean. Perhaps this will communicate that better?

Suggested change

	[=controller=] of a [=verification method=], the actual [=controller=] can generate
	proofs that satisfy the method.
	<em>actual</em> [=controller=] of a [=verification method=] —
	which the `controller` of the [=controlled identifier document=]
	may not have <em>asserted</em>
	as the [=controller=] of the [=verification method=] —
	can generate proofs that satisfy the method.

I have suggested alternative wording to the above which I hope makes it clearer to readers.
