thanks for link! however looking on WSDL used in this interop (at the 
end of the document) how one can determine that service supports 
WS-Addressing? WSA is not mentioned in the WSDL ...

unfortunately Working Draft: 2002-04-13 (looks like typo it should be 
probably 2005 in http://www.w3.org/2002/ws/addr/): Web Services 
Addressing 1.0 - WSDL Binding 
<http://www.w3.org/2002/ws/addr/5/04/wd/WD-ws-addr-wsdl-20050413/> is 
not publicly available (password protected) - is there somewhere 
publicly accessible version? is it different form what i had 
(http://www.w3.org/TR/2005/WD-ws-addr-wsdl-20050413/)? is there 
something new in the latest editors' version?

thanks,

alek
