Synopsis: The current description of the Reliability QoS settings allows the

          possibility of modifying QoS values in a way that would violate

          validation rules. The issue submitter proposes to add the following

          text to the "Reliability" description on page 54 after paragraph 3:



          "The validity of quality of service reliability level modifications

          depends on the state of Notification Service objects. In general,

          reliability levels may not be modified after a "child" object has

          been created. Such modifications may violate quality of service

          validation rules of the Notification Service."



          "Specifically,



                - modifying the event channel reliability setting through

                  set_qos after ConsumerAdmin or SupplierAdmin objects have

                  been created is invalid, and



                - modifying the ConsumerAdmin or SupplierAdmin reliability

                  settings through set_qos after proxy supplier and proxy

                  consumer objects are created is invalid.



Disposition: I personally do not have any real objection to these proposed

             restrictions on implementations, but I'm not entirely convinced

             they are necessary. We have had extensive e-mail discussions

             about this issue, and I've never fully been convinced that these

             changes are necessary. I would probably vote "abstain" on a vote

             for this issue, and leave it to the consensus to determine whether

             or not to incorporate the proposed changes.



VOTE: YES means to make the changes recommended by the issue author.

      NO means to do nothing.

The current description of the Reliability quality of service settings
allows the possibility of modifying quality of service values in 
a way that would violate validatation rules.

Proposed change:
================

To add to "Reliablity" text, Page 54 after paragraph 3.

The validity of quality of service reliablity level modifications
depends
on the state of Notification Service objects.  In general,
reliablility
levels may not be modified after a "child" object has been created.
Such modifications may violate quality of service validation rules
of the Notification service.

Specifically,

        - modifying the event channel reliability setting through
set_qos
          after ConsumerAdmin or SupplierAdmin objects have been
created
          is invalid, and

        - modifiying the ConsumerAdmin or Supplier reliability
settings
          through set_qos after Proxy Supplier and Proxy Consumer
objects
          are created is invalid.
