+<p>A URI string.  This is identical in format to atom:String, except the string
+is a URI.  This is occasionally useful when a URI is needed but mapping it is
+inappropriate.  URIs should never be expressed as atom:String, because this
+makes it impossible to distinguish URIs from arbitrary strings, which makes
+functionality like mapping or rewriting URIs impossible.  Similarly, there is
+deliberately no atom type for filesystem paths.  To refer to a filename, use a
+complete file URI, with hostname if at all possible.  This allows hosts to
+properly handle paths in situations like serialisation or network
+transmission.</p>
