Text.RSS

A libary for generating RSS 2.0 feeds.

Original module by Jeremy Shaw.

Changes by Bjorn Bringert:

• showXml just converts the RSS to a String, does not print it.
• Added XML escaping.
• Use RFC 2822 format for dates.
• Added all elements from RSS 2.0.1-rv-6, http://www.rssboard.org/rss-2-0-1-rv-6
• Use HaXml.Verbatim instead of HaXml.Pretty, since HaXml.Pretty seems to introduce spaces around entities.
• Removed the use of content:encoded, since the description tag is the recommented way to include HTML content in RSS 2.0.

Changes by Bas van Dijk:

• Use UTCTime from time instead of CalendarTime from old-time.
• Add our own Weekday type instead of using the Day type from old-time.
