Use of ONIX code list 196 - codes 08 and 09 - Unknown accessibility / not accessible

[chrisONIX]

In ONIX code list 196 - there are two codes that can be used by a publisher / creator to indicate in the case of code 08 - Unknown accessibility. In the case of 09 - Inaccessible, or known limited accessibility. Both of these codes can be accompanied by a short text to explain. In the case of 08 - the feedback from publishers is that they will use this code when a title is not yet assessed or they do not yet have the information - but these titles may already have been announced in the supply chain. In the display guidelines should we mention these two cases. In the case of 08 - Unknown accessibility - this is very much an example of where a publisher will later send an updated ONIX file with accessibility information. There is an intention to particularly use this for older ePub titles awaiting evaluation and also for PDFs.

How should we approach these cases in our guidelines?
