One reason it is now difficult to relate the terms "resource identifier"
and "reference to a WS-Resource" is that I removed (per the resolution to
issue 127) the following text which related these 2 concepts:
"An identifier of the resource MUST be represented in any reference to a
WS-Resource. and MUST appear as part of any message to a WS-Resource to
allow the WS-Resource to disambiguate the resource targeted by the message.
The precise location of the resource identifier in a message to a
WS-Resource is dependent on the protocol binding used to interact with the
WS-Resource endpoint but is normatively defined in the appropriate
WS-Addressing binding specification. For example, [WSA – SOAP] defines the
binding of message addressing properties for the SOAP protocol."
It is not clear to me that this text repeats any part of WS-Addressing - it
is a description of the WS-RF usage of EPRs.
I would agree with Kirk's observation and suggest that we reinstate some or
all of the above text. At the very least, it would seem that we should
still state: "An identifier of the resource MUST be represented in any
reference to a WS-Resource. "
Comments?

The reason ResourceIdentifier is NOT used is that an EPR does not
provide "identity" for a resource. An EPR is only a reference to a
resource.
The use and rules associated with reference parameters is covered in
WS-Addressing and should not be covered in this spec.

There now seems to be three concepts used with the space two pages:
Resource Identifier
Reference to a WS-Resource (which is structurally tied to
WS-Addressing)
And, in the SOAP example: SomeDisambiguatorElement
These three concepts are never explicitly related to one other.
Obviously, SomeDisabmiguator is part of the reference to a WS-Resource
(ReferenceParameters). Further, I assume, after carefully trying to
connect things that are in the text, that the Resource Identifier is at
least one possible "disambiguator element". If so, would be clearer to
use <ResourceIdentifier>R1</ResourceIdentifier> rather than
<SomeDisambiguatorElement> in the example? After all, the text does say
that "R1" "identifies" the resource
