These will become relevant once the reorg is done; we may have to review them after that. I do not think we could do this at the next call, when the reorg will be still fresh; but we could decide on the week after and/or on emails. This should be part, actually, of a larger discussion on closing the open issues before we start a new round; these use cases are just part of the issue review (ie, they are not mine...).

Yes, I think the important point is that the author/publisher should be able to put enough information on this into the WP.

:-) I actually believe it is more than that. If a WP is implemented, in its full beauty, via an extension, for example, then this use case may lead to some important design decisions.

I haven't yet compare it to the latest version of the UCR to check whether these are really new requirements (at first glance they look like it) also because that document is still kind of a moving target. However, I did not want to unnecessarily pollute the github repo either; so I copy the 4 use cases I extracted in the mail below for first sanity check. I will put as explicit issues the ones that we agree upon as o.k. (any linguistic/grammatical changes are welcome); we can then take care of them when both Leonard and Heather declare victory in the big set of changes.

However, not all user agents are necessarily WP aware. Nevertheless, the structure of a Web Publication should provide a graceful degradation for these cases and not make the presentation of the publication impossible.

However, he is working from behind a corporate firewall, which does not allow him to install the necessary browser extensions to manage all features of a Web Publication. Nevertheless, even without this extension, he is able to get to the essential information of the document which allows him to do his work.
