View template does not pass accessibility checks.

Table that displays event details is missing the attributes for scope. I believe this was fixed in a previous version by not using a table, but it appears to have regressed to the tabled version.

@cthomas1978 can you point me directly to the problem? we're using not tables but a dl/dt/dd structure in https://github.com/plone/plone.app.event/blob/master/plone/app/event/browser/event_summary.pt
