Hi Tony,

Thanks. The WG has addressed many of the details of the issue (and  
reasonable people can disagree on their resolution), but not its  
overall substance.

I'm not lie-down-in-the-road against the HTTP binding -- even if I  
don't think it's a great solution for the problem space -- provided  
that there were actually interoperating implementations of it, and  
people wanted to use it for itself, not just with the SOAP binding on  

However, I don't see that this is the case. So, I'm not satisfied by  
the proposed resolution. Note that I don't expect the WG to spend  
more time on this; closing the issue and marking it for discussion  
during the transition meeting would be adequate.

Kind regards,
