The tool has properties which represent site-wide defaults for the
interval, etc.  I don't really care about making those editable in the
"front side" of the tapestry (the CMF UI) rather than the "back side"
(the ZMI).

There is no interface to which one could look up an adapter to find such
a policy:  you would potentially need separate marker interfaces, and
duplicate registrations, for every folder in your site.  The syndication
info objects are *data*, not *code*:  the represent setttings in a
place.  The tool uses them to figure out values for the syn:-namespace
elements in the RSS.
