Subject: Proposed resolution for Rel-32
Here is a proposed resolution for Rel-32:
Add the first seven definitions in Requirement document
at Section 3.2 Definitions to the Specification
at 1.8 Terminology.
Thanks,
Iwasa

Title: Add new terms from requirments
Description: See resolution for definition issues.

Requirement document:
3.2.Definitions
The Specification :
Denotes the future WS-Reliability specification that is the
output document of the Technical Committee.
Reponse RM-Reply Pattern :
We say that a response RM-Reply pattern is in use if the
outbound Reliable Message is sent in the underlying protocol
request and the Acknowledgment Message (or RM-Fault
message) is contained in the underlying protocol response
message corresponding to the original request.
Callback RM-Reply Pattern:
We say that a callback RM-Reply pattern is in use if the
Acknowledgement Message (or RM-Fault message) is
contained in an underlying protocol request of a second
request/response exchange (or a second one-way message),
operating in the opposite direction to the message containing
the outbound Reliable Message.
Polling RM-Reply Pattern:
We say that the polling RM-Reply pattern is being used if a
second underlying protocol request is issued in the same
direction as the one containing the outbound Reliable
Message to act as a request for acknowledgement. The
Acknowledgement Message (or RM-Fault message) is
contained in the underlying protocol response to this request.
This polling pattern is expected to be used in situations where
it is inappropriate for the sender of reliable messages to
receive underlying protocol requests.
Fault :
A fault is a physical defect, imperfection, or flaw that occurs
within somw hardware or software component.
Error:
An error is a manifestation of a fault. Specifically, an error is a
deviation from accuracy or correctness.
Failure :
If an error results in the system performing one of its
functions incorrectly then a system failure has occured.
Fail-stop model:
A fault is said to be fail-stop if whenever it occurs, the only
visible effect is that the affected component stops
functioning. Thus, any component affected by a fail-stop
failure can show no incorrect or arbitrary behavior.
Byzantine fault model:
A failure is said to be byzantine if whenever it occurs, the
affected component can show any arbitrary, thus possibly
malicious, behavior.
Crash failure:
Crash failure (or simply Crash): Any failure that is
consequence of a fail-stop fault.
Crash Tolerance:
Crash Tolerance is the ability of a system (either only
specified or a software/hardware implementation) to ensure
predetermined properties despite the occurence of one or
more unpredictable crash failure.
Failure Recovery:
Failure recovery is the process of regaining operational status
or restoring the system's integrity after the occurance of a
failure.
