actually, 2 things are fixed:
what i was getting was <item/>
what i should get is <li rdf:resource="uri"/>

getAbout() seems to be empty.  even when i used it first with the
li tag, i got <li rdf:resource=""/> or <li/> (when EXML nicely ignored
an attribute with a null value).

again, if the about property isn't set by something, its empty and that's
causing problems.  My reading of the O'Reilly article is that the uri needs
to be the same as the one in the Item tag, so why not use getLink in both?.

The reason is that in RDF, the order of elements technically doesn't matter,
unless the elements are wrapped in an rdf:Seq container.  Even if RSS 1.0
were to specify that that the Item tags are in the right order, to be RDF
compliant (which I need to work with existing RDF tools here @ my company),
the Seq is all that matters in the order of things.
