  To make this meaningful, do we need more discussion of what "merge"
means, or should this be left entirely to clients?  I'm inclined to
think we need a good description of the expected range of application
and motivation, and the rest can be left to specific applications.

  This syntax seems reasonable; I presume we'll want to include some
way to mark multiple <merge/> sources with priorities to determine
"who wins" in the presence of multiple sources for a bookmark; some
applications will present all versions of a bookmark and others will
only want to present one but make the determination based on the
bookmark data.
  I presume this <merge/> element should be allowed in both <xbel/>
and <folder/> elements.  Do we want to do this in XBEL 1.1 or wait for
more experiance before adding it?
