.. this is a comment line, using the RsT line comment marker.
.. Keywords are delineated with colons(:).
.. :order of these keyword entries is not important.
.. :cite: for citations to published sources
.. :url: for URLs to relevant web pages.
.. :rel: for relations to other zettels.
.. :child: id of child zettel.
.. :time: 1830
.. Body of note is not introduced by any identifier.

This format is basically the same as Format 2, except that the keyword lines start with a colon (:).  RsT automatically renders them in a nicely readable way.  Also, comments are delineated using the RsT comment marker ("..").

Note that Markdown does not have a convenient syntax for the inline keyword lines or for comment lines.  This makes me think that Restructured Text is the best way to go for zettels.

**Pros**: Uses only standard RsT syntax.

**Cons**: *Slightly* more typing for the keywords and comments, compared with plain text format version.
