ebBP 3/21/2005: Comment re: Business Retries (wd10/schema 2-22)

["Monica J. Martin" <Monica.Martin@Sun.COM>]

 From Sacha Schlegel: Why are no business retries specified on 
Notification and the extensible DataExchange elements, even though they 
can be specified on all other patterns? In reviewing the historical 
material and our disucssions, I can see why we should be consistent. It 
is a bit confusing to retry a Notification (of Failure) but that may be 
only to me. 

Open question for Schema:

    * Determine if we add all the associated attributes including retry
      count on both Notification and DataExchange.

      <xsd:attribute name="*isAuthorizationRequired*"..../>
      <xsd:attribute name="*isIntelligibleCheckRequired*"..../>
      <xsd:attribute name="*isNonRepudiationRequired*"..../>
      <xsd:attribute name="*isNonRepudiationReceiptRequired*"..../>
      <xsd:attribute name="*timeToAcknowledgeReceipt*"..../>
      <xsd:attribute name="*timeToAcknowledgeAcceptance*"..../>
      <xsd:attribute name="*retryCount*"..../>

Proposed changes for Technical Specification:
Section 4.8.2.3:
===========
Change from: The business retry for a RequestingBusinessActivity 
identifies the number of retries allowed in addition to the initial 
request while the time to perform has not been exceeded.....For example, 
if a business retry was not specified and a response was not received, 
an NOF could be issued. If the response is received, it is then ignored 
because the NOF has negated the business transaction. 

Change to:
The business retry for a RequestingBusinessActivity identifies the 
number of retries allowed in addition to the initial request while the 
time to perform has not been exceeded.....For example, if a business 
retry was not specified and a response was not received, an NOF could be 
issued. If the response is received, it is then ignored because the NOF 
has negated the business transaction.  In another circumstance, if any 
business exceptions (includes negative receipt and acceptance 
Acknowledgments) are signaled then the business transaction SHOULD 
terminate and no business retry SHOULD occur (even if parameter is other 
than zero).

Section 4.11.3.4
[add to bulleted list of well-formedness rules for "Business Signals"]

    * If a Negative Receipt Acknowledgement or Acceptance
      Acknowledgement occurs, no business retry SHOULD occur.
