[chrisONIX]

This may have already been covered but in case it has not - should the principles document - User Experience Guide for Displaying Accessibility Metadata 2.0 - in the section 1.1 Publisher metadata ecosystem have a sentence or two about how metadata , especially in ONIX, will be updated during the lifecycle of a product for various reasons, so that displayed metadata will also have to be updated accordingly.
