I should correct what I said below to draw the distinction between RDF and RDF/XML:

One does have to maintain a consistent RDF structure because the XSLT is
a "dumb" static file, but if your RDF is being generated systematically,
it will probably have a consistent format anyway.  It also means that a
human has to use "view page source" to look at the underlying RDF, but
  
This should have said, "maintain a consistent XML structure ... if your RDF/XML is being ..." since XML is just one way of serializing RDF.  However, it is the recommended serialization of RDF for GUID resolution, i.e. the GUID A.S. rec 10 says "The default metadata response format should be RDF serialized as XML." (emphasis in the document), so people following the rec will be generating it.  What I was trying to get across is that there are easy ways to create human-friendly representations.
