+      <dd>A whitespace-separated list of IRIs identifying specific constraints

+        knowledge, so that clients both with and without knowledge of a profiled
+        resource can safely use the same representation. The <code>profile</code>
+        parameter MAY also be used by clients to express their preferences in the
+        content negotiation process. It is RECOMMENDED that profile IRIs are
+        dereferenceable and provide useful documentation at that IRI. This
+        specification, however, does not define any formats for such profile
+        descriptions.
