As far as I can tell, this decision has basically no effect on WSRF.
The argument being made by some in the WS-A working group is that it is
equivalent and more true to the Web to carry a resource identifier as
part of the EPR address, rather than in a separate ResourceProperties
field -- that is, the resource reference should all be in the URI,
rather than split between a URI and separate resource properties.
Implementation-wise it certainly makes very little difference. And the
WSRF working group had already abstracted the WS-Resource reference and
access pattern, so that it is not tightly coupled to WS-A and reference
properties anyway, so WSRF specification-wise it makes no difference.
