RDF reification and lists do *work* in RDFa, they're just a bit of a
pain to mark up.

e.g. here's a reification:

<div xmlns:dc="http://purl.org/dc/elements/1.1/"
  <span property="dc:creator">Mark Birkbeck</span> says that
  <span rel="rdf:subject" resource="[db:Sky]">the sky</span>
  <span rel="rdf:predicate" resource="http://dbpedia.org/property/color"
  <span rel="rdf:object" resource="[db:Blue]">blue</span>.

And an example of a list can be found here:
