Right, and maybe we only need "none". The cases -- knowing your content is
inaccessible, not checking, or not wanting to say -- all boil down to saying
no features are known to be present.
I don't see how you could get in trouble for your content being more
accessible than you've indicated, at any rate.

Subject: Re: [a11y-metadata-project] accessibilityFeature none
Yeah, this is similar to the alt=''. Did they forget to put a value or are
they saying it's not needed? So, I think similar to how a role property
with a value was created. I think it makes sense to use the existing
accessibilityFeature property with a value of none. We should decided
quickly as some publishers will soon be inputing properties into the
Learning Registry and I want to provide an updated best practices guide.

One question that’s been raised in the edupub work, where we’re looking at
integrating the metadata, is how to make a statement either that no
accessibility features are included, or that the publisher wants to
explicitly disclaim that, while some may be present, they are not making any
claims about the suitability of the content (whether for legal reasons or
otherwise).
Omitting the property might indicate no accessibility feature, but it might
also mean that the book was not checked.
In that light, should we have (or tacitly allow) none/notVerified values for
this purpose?
Part of the rationale for such values is also that it would allow us to
require accessibilityFeaure appear in all edupub-compliant epubs, as they
address the implied cases of no properties being set.
I’m not sure where I stand on this yet, so thoughts welcome.
