is that only elements in the rdf namespace?  Ah no. there is an example in 
another namespace.

As I recall, a concern was about defining names not in the rdf namespace, e.g.

   <foo:bar about="...">

We talked about deprecation but were advised against by DanC.  In practise 
parsers will be tolerant of this input unless they are set to strict mode 
and that seemed like a reasonable migration strategy.  We could add a note 
to they syntax doc suggesting that parser writers be aware.

On the other hand, I personally agree that is a change to M&S and perhaps 
we can find some other way to deal with it.
