[Pgi-wg] Sec: Agreement on WS-Naming (ref by strawman)

[m.riedel at fz-juelich.de]

Ok,

  I understand much better know.

So I see a demand that we discuss if our services are contacted with WS-Addressing or not. 

Q: How does ARC services then distinguish one instance from another if only one URL is used?! you don't seem to use referenceproperties then, instead adding to the url resource-instance ids?!

Take care,
Morris
