RSS 3.0
Introduction (you should probably read it first). This spec is not yet finalized. Feedback appreciated.
Format
An item consists of a series of lines separated by "\n".
Each line is a series of letters, numbers, "-", "." or "_" (called the name) followed by ": " followed by a series of characters (called the value). No two lines should start with the same name. If a line starts with a space or tab character, then it is a continuation of the value on the previous line. The newline in between is preserved. UTF-8 encoding is always used.
An item ends at the first blank line (that is, a line with no characters).
Document
An RSS 3.0 document consists of one head item followed by zero or more body items.
