RTMLAttributes 

<P>The attributes potentially needed by every RTML element:
  <UL>
    <LI>id (local key of an element), the normal XML id with the normal XML constraints (not many non-alphabetic characters allowed!);</LI>
    <LI>ref (reference to local id (e.g. ref="myID");</LI>
    <LI>uref, a reference to a non-local unique id of a document plus optional reference to a ref within the document (e.g. uref="rtml://DE.Uni-Goettingen.MONET/abcdefg#myID").</LI>
  </UL>
</P>
<P>Changes:
  <UL>
    <LI>2009-JUN-26: added rdf to let one label elements as RDF/SKOS vocabulary terms.</LI>
