clarification on "feed" field in metadata - data.json

[kachok]

Page - http://project-open-data.github.io/schema/

Feed filed is defined as:
"URL for an RSS feed that provides access to the dataset." - in the beginning of document
"These RSS feeds will be used to create a cross-agency RSS feed search tool." - at the bottom of the document.

What exactly does it mean? Is it RSS feed with news about dataset? Or dataset itself is just RSS feed (let's say from agency blog).

How cardinality is expressed for this field? e.g. how I reference multiple RSS feeds? (can't comma separate them, since comma character is valid in URL)

After much good discussion, consensus was to remove the "feed" field because it's easy enough to automatically parse the data.json file to surface entries with a format of "rss". See #44 for the change. Thanks!
