Appcast item - support extensions with custom XML elements #13
Description
The original Appcast implementation in Objective C supports reading of all additional (unrecognized) XML elements in the <item> tag.
This feature was removed because the SUAppcastItem.propertiesDictionary was not compatible with the sendable rules.
The SUAppcastItem can use a different approach and report all unrecognized XML elements with their value and attributes as string-only values.
