ping on xpath op namespace for RIF

Back on March 5, you asked some difficult questions in response to my
earlier questions about an xpath op namespace [1].  Since I didn't have
good answers to your questions, I asked someone else from RIF to help,
and Jos de Bruijn kindly did, on March 28 [2].  I understand things get
busy, but we expect to proceed to Last Call with this in a matter of
weeks.  At this point, I expect we'll proceed using
"http://www.w3.org/2005/xpath-operators" as a namespace for the xpath
operators.  Your alternative design approaches, while probably viable,
do not appear to meet our needs as well as simply picking a namespace
name.
