-   This element is meant to provide alternate versions of an enclosure, such as low or high bitrate, or alternate formats or alternate uri schemes, like IPFS or live streaming.  There may be multiple alternateEnclosure elements in an item, but there must be no more than one in a channel.  The presence of this element at the
-   channel level would be useful for adding a video/audio trailer or intro media that introduces the listener to the podcast.  For instance, in a podcast of an audiobook, this could be the book's
-   introduction or preface.  The alternateEnclosure element always refers to an "alternate" media version.  The standard RSS enclosure element is always the default media to be
-   played.

-   All attributes are required except for "stream".  "stream" is a boolean attribute that indicates the uri points to a streaming media that is not downloadable.
