We have been running podcasts for years, but generally didn't both much with worrying about our RSS feeds being compliant. But increasingly people are complaining that none of our Plone sites (4.3 or 5.1) are working well with their RSS readers. And we recently tried submitting some test podcasts to iTunes and other read feeders, and they all fail.
We have RSS feeds fully enabled, they are detected, but it appears they are basically 10+ years out of date with current podcast RSS feed standards? Is there a means of tweaking either Plone 4.3 or 5.1, or an add-on, to make it so that the RSS feeds become at the very least compliant with iTunes podcasting requirements? https://help.apple.com/itc/podcasts_connect/#/itc4f0f5ac7d
