Re: [ebxml-msg] Fw: Old comments (outstanding since 1.09)
Doug:

 

I have a hard time following your line number references. I 
looked at the Word document online and also printed out a hard copy. The 
frustrating thing is that the line numbers I see in the online Word document do 
not even match those in the printed copy. In many instances, your referenced 
line numbers match neither the online Word document nor the print 
out.

 

Does anyone else encounter such line numbering problem? I am 
using the version obtained from http://lists.oasis-open.org/archives/ebxml-msg/200201/msg00055.html 
viewed without change bars.

 

Thanks,

-Arvola

Subject: [ebxml-msg] Fw: Old 
  comments (outstanding since 1.09)

  
The following material includes issues I've raised in the 
  past but have not been discussed on the list or addressed in the 
  specification.  I've edited the list to remove things no longer relevant 
  or already handled.  The line numbers are for the 2.0 document in PDF 
  form (or Word form without change markings) and the suggestions start from the 
  current text. 

  
The historical messages of interest are "[ebxml-msg] Comments 
  on 1.09 first half" [1],"Re: [ebxml-msg] Comments on 1.09 first half" [2] 
  (added point about missing section 4.2.1) and "[ebxml-msg] Comments on 1.09 
  second half".  (My comments on the 1.09 schema were generally applied 
  correctly but for the problems already mentioned in Chris' email.)

[2] http://lists.oasis-open.org/archives/ebxml-msg/200111/msg00346.html 
[3] http://lists.oasis-open.org/archives/ebxml-msg/200111/msg00351.html 
  
General: 
  
    
Unless specifically called out to the contrary, all issues 
    below are editorial. 
    
Anything (maybe, almost anything) at the end of a line in 
    square brackets is added explanatory comments or suggestions to the editor 
    which should not appear in the specification directly. 
    
I found a fair number of incorrect references to sections 
    in the document.  Why doesn't this document use links to correct 
    sections so that edits don't mess them up? 
    
Comments below suggest(ed) adding references to 2.3.6 (then 
    2.2.6) where they were missing in the 1.09 document.  The 2.0 document 
    instead contains no references at all to 2.3.6.  Only the schema 
    describes where wildcard element content is allowed.  (The schema does, 
    at my suggestion, allow <any> element content on all top-level SOAP 
    extensions and the Error and Reference elements we define.)  I'd 
    recommend restoring the "#wildcard" lines from 1.09 and adding those 
    mentioned below. 
thanx,

  New comments noticed while doing this comparison: 
  
    
The word "then" appears often instead of a comma.  The 
    document might be significantly shorter the other way. 
    
223 s/normative/non-normative/ [This 
    and following addition are a TECHNICAL change necessary to avoid problems 
    with contradictions between Appendix A and the schema available directly 
    from the web site.] 
    
224 a 
The XML Schema document found at http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-2_0.xsd is a normative part of this specification and supersedes the 
    "snapshot" found in Appendix A. 
    
228 Section 1.1 is missing.  Suggest adding "1.1 
    Background" or some such. 
    
618, 621 Move these lines to the left to line up with other 
    URI values called out in the specification.  I guess it made sense to 
    remove the background highlighting these lines (because it was also used for 
    examples).  Unfortunately, the removal of that attribute messed up the 
    indentation. 
    
779-781 [TECHNICAL: Remove second 
    sentence.  It's not possible (or worthwhile) to determine whether or 
    not something is a URI except by checking for a colon.] 
    
877-880 
    [TECHNICAL: This section on the Timestamp element doesn't require any 
    particular precision for the value.  All examples in this document are 
    accurate only to seconds, likely not enough for reliable ordering of 
    received messages (among other purposes).  Timestamps generally include 
    at least milliseconds and we should be at least that 
    prescriptive.] 
    
1049,1053,1065,1068-1072 [To be 
    consistent with the typographic changes to sections 2.3.1 and 2.3.2, 
    removing the background from non-example material in section 4.1.3 would 
    seem appropriate.  The lines referenced in this issue are the remaining 
    cases of normative material against a grey background.  That background 
    should be removed.] 
    
1114,1116 s/&quot;/"/g [No reason 
    to use the character entity for quotation marks outside an attribute 
    value.  Just lessens readability of the example.] 
    
1407 Section 6.1 is missing.  Suggest making 6.1.1 
    through 6.1.5 be 6.1 through 6.5.  Chapter 6 has no lower or later 
    sections. 
    
1486-1487 s/or by leaving this attribute out.// [TECHNICAL: I suggested adding a default actor option to the 
    AckRequested and Acknowledgment elements.  Later in the discussion, I 
    was convinced by others in the group this wasn't a necessary addition and I 
    withdrew it.  Since the sender doesn't know whether another MSH is 
    authorized to act on behalf of the To Party, toPartyMSH is enough.  The 
    document and schema unfortunately followed my suggestion and not its 
    withdrawal.] 
    
1529-1530 Remove last sentence in paragraph.  [Reasoning as above.] 
    
1713 s/Acknowledgment Messages/Acknowledgment Messages

    together with a business response, maybe an ErrorList (containing warnings) 
    too.  Improvement may require some text changes earlier in the 
    document as well.]

    an exclusive choice.  None of the elements defined in this

    wildcard elements are provided wherever extensions might be required for 
    private extensions or future expansions to the protocol. 
Note: 
    Extension elements should be included in ebXML SOAP extensions only when 
    they expand the semantics of that particular element.  This mechanism 
    might be used, for example, to extend the eb:Error element by providing 
    additional structured information about a problem.  Wholly new features 
    should be implemented using separate SOAP extensions.

For all ebXML SOAP

    (unlike lines 717-722 I'd recommend we delete).] 
2.3.10 SOAP actor 
    attribute 
All ebXML SOAP Header extensions defined in this specification 
    that may be handled by an MSH node other than the ultimate recipient of a 
    message allow inclusion of the SOAP actor attribute.  If present, this 
    attribute SHALL have one of the values defined in the following two 
    subsections or the SOAP-defined value http://schemas.xmlsoap.org/soap/actor/next. 
    
[I've been told the actor described in existing 
    section 2.3.11 will support an intermediate node acting on behalf of the To 
    Party in returning an Acknowledgment (prior to the ultimate recipient seeing 
    the message).  That's a great use case, handling (for example) trusted 
    store and forward MSH implementations in the destination's DMZ.  If 
    that's the case, we need to be clear this actor value is specifically for 
    use in the AckRequested and Acknowledgment elements.  I don't think 
    it's useful elsewhere. 
Changing the above 
    last sentence to read "If present in the 
    AckRequested or Acknowledgment elements (see sections 7.3.1 and 7.3.2), this 
    attribute SHALL have one of the values defined in the following two

    regardless of the highestSeverity and the problem is mostly addressed 
    through the two changes above.  In addition, "processing" is used in 
    the first paragraph without context and we still need to remind users that 
    ErrorList with highestSeverity="Error" can't be combined with payload 
    data.  Something at the end of the first paragraph like "This method MUST NOT be used if the highestSeverity is 
    "Error".  No further processing of the message in error could have 
    occurred in that case." may help.]

    allowed if syncReplyMode is none (for the Acknowledgment message to come 
    back synchronously); if syncReplyMode is not none and it's a synchronous 
    communication protocol in use, SyncReply MUST be present.  Further, 
    intermediaries may have no idea about the CPA in use and could easily 
    violate these overly strict restrictions (e.g. an intermediary just prior to 
    the To Party requesting a synchronous hop-to-hop Acknowledgment).] 
    
[TECHNICAL issue: During the discussion of 
    this addition we agreed to add words about SOAP processors w/o full MSH 
    understanding and their need to forward a like extension.  Those words 
    are missing.  Note: Intermediate MSH nodes MAY forward using a 
    different protocol than the incoming message and are therefore NOT REQUIRED

Section 7 
  
    
1426 a 

  
    
For the purposes of this document, "Reliable Messaging" is 
    defined to mean sending a message that both parties will know was received 
    by the To Party's application intact once and only once, detect a permanent 
    failure situation or retry until giving up. 

    
Note: Failure remains an option even when making full use 
    of ebXML Reliable Messaging.  In addition, this addresses duplication 
    only when caused by errant MSH implementations or communication protocols: 
    Applications may send distinct messages containing the same payload and 
    receiving applications may need to handle these duplicates. 
  

  
    
1429 s/flexible/flexible with respect to intermediaries/ 
    
    
1429 a 

  
    
The protocol is also flexible with respect to the features 
    implemented by communications protocols, ebXML MSH software and 
    applications.  Options are available controlling MSH implementation of 
    well-defined segments of the overall reliability requirements.  Most of 
    the following discussion assumes all ebXML reliable messaging options are 
    enabled. 

    
Note: This assumption in the text should not prevent use 
    of reliable communication protocols, idempotent application semantics, et 
    cetera instead.  ebXML Reliable Messaging semantics should be 
    considered whenever such alternatives are not available or the MSH 
    implementation is more efficient. 

  
    
1435 s/once/once (due to retries or the nature of the 
    communications protocol in use)/ 
    
1436 a Retries initiated by a Sending MSH and duplicates 
    introduced by an unreliable communication protocol MUST be handled by the 
    Receiving MSH or higher application layers at the To Party. 
  
Section 7.1 
  
    
1443 s/SHOULD/MUST/ 
    
1455 a [TECHNICAL: All of the following 
    information is presently missing which is internally inconsistent.] 
    

  
    
In order to associate an Acknowledgment element with the 
    corresponding application state and to send retries, a Sending MSH SHOULD 
    save the following in persistent storage: 

  
    
      
MessageId of the sent message 
      
Timestamp, RetryInterval and remaining Retries (elements 
      and parameters to the MSH), providing support for a queue of messages 
      awaiting retry or application failure notification 
      
Entire SOAP message for use in later retries 
      
links to application state for any required notifications 
      

  
    
The possible notifications from a Sending MSH to the From 
    Party application are: 

  
    
      
Successful delivery (Sending MSH has received an 
      Acknowledgment element in a message not containing an ErrorList) 
      
Acknowledged delivery with errors (Sending MSH has 
      received a message containing both Acknowledgment and ErrorList elements; 
      processing MAY have continued at the To Party in this case) 
      
Timeout (TimeToLive expired or Retries have been 
      exhausted)

    I disagree with this requirement because it disallows the To Party MSH 
    acknowledging receipt of a message and signing the acknowledgment without 
    also describing the contents.  The message already has the 
    RefToMessageId element and any disagreements about the contents of that 
    message would be covered through the signing the original party did.  I 
    would prefer to strike this sentence and much of the surrounding 
    discussion.  It's a bit worse now that the text attempts to define 
    "signed Acknowledgment Message" two ways simultaneously (signed Ack either 
    means "it contains both Ack and Signature" or "contains both Ack with 
    Reference list and Signature").]
