They are indeed, XML namespaces fixed one problem calling different 
things by the same name  but  they created another problem of calling 
the same thing by different names, Prefixes are not themselves bad, 
misunderstood  or any kind of indirection mechanism, they are just short 
hand urls, they are actually quite intuitive if used correctly.  RDFa Is 
currently trying to solve its problems with xmlns, is just a minor 
design flaw, xmlns is used for structure not content and they realize 
that issue.
