It's a pretty well-known format for bookmarks, and is the native
bookmark format for several browsers. Revising XBEL to create a v1.2
compatible with existing software seems a much more productive route
than devising a new format.

One man's "not under active development" is another man's "stable".

There is a <desc> tag suitable for summaries. Keywords/tags can be
stored using <metadata> (there's an example of using <metadata> for
tags here - http://www.xml.com/pub/a/2005/03/02/restful.html). There is
an "icon" attribute on <folder> and <bookmark> elements, though it's
not a URI, so may be of limited utility.

The same xml.com article I linked to above (which is the first hit on
Google for 'xbel example') contains an example with nested <folder>
