Is it possible to add custom metadata to an Atom feed, without breaking compatibility with feed readers?
I've added a custom namespace and custom elements to my feed, but Safari now refuses to read the feed, stating that “The feed could not be loaded because the content is not in a known feed format”.
I need this metadata in a custom application that loads the feed, but I want other feed readers to simply ignore these extra elements. Is that possible?
Excuse my ignorance, I'm a Cocoa developer and I know very little about this new-fangled interweb stuff...
