And since individual semantics like rearnote, footnote, endnote, *ref are not true Landmarks, we should design an easy way to just add structural epub:type attributes to individual non-Landmark level tags.

I am thinking of an extra clips-like bar that is pre-filled in with these attribute strings (and not user editable) that could add these non-Landmark/Guide level individual attributes to the current cursor location in CV.

Perhaps we could extend that interface to add aria-roles in a similar way?

Of course a user could use his/her own clips bar for that but a dedicated single-click one might be nicer.

This would only be to add the additional epub 3.3 structual semantics that are not Guide/Landmark level but instead are meant to indicate a role for an individual tag.

Thoughts anyone?
