I believe we have overlooked an issue. The technique documents have final IF/THEN/ELSE statements to handle the absence of any claim by declaring a negative (e.g. "Appearance modifiability not known", "The publication does not include a conformance statement").

From a distributors perspective we are creating a 'claim' that the publisher never made.
From a consumers perspective we have placed a 'claim' into the record for that title, such that when searching a catalog for items with an accessibility claim, this 'created' claim will show up, yet it is not something the publisher created.

We need to put in some guidance that while we may recommend that the output of the technique calculations may result in the creation of a 'claim' that was not received from the publisher, users of the specification may want to (or need to, depending on their contractual obligation to publishers to only show what they received) choose to keep any claim for that key accessibility information category empty, rather than create a 'claim' statement that the publisher did not provide.
