MRSS

This was a submitted suggestion for RSS feeds with complex multi-part data (e.g. a chart show of music) to permit podcatchers to jump to other elements inside the feed. The original content is lost now (I might be able to dig out the original text) but the basic detail is that you serve your RSS feed as normal, and add two new sections to your feed.

PartWork

Entries marked <mrss-plus:partwork> would hold data about that element of the show.

FullWork

Entries marked <mrss-plus:fullwork> would hold data about alternative formats, file lengths, have sha1 hashes of the file, etc.
