We realize that this is a difficult area, but we believe that it would
be  a  mistake  for  W3C to move forward with a new version of the RDF
specifications  without  undertaking  the  work  of  a revision of the
syntax.

We  regret  that we must dissent formally from your resolution of this
issue.  The  current mismatch between RDF syntax and off-the-shelf XML
tools  has  not  become  easier to bear as time goes on; we believe it
must be addressed.
