 Mark,

Apologies .. I retract the comment about missing questions, find the spec attached with answers to your comments ( annotations ). This supplements the other email threads.

BTW - Don't feel you have to justify your position with vague comments like .. " I know that HP is not the only company on the committee that feels the same and that others have expressed this in same concern in face-to-face meetings" .. I would expect the other participants to openly express their opinions in a constructive manner, I have very thick skin and an equally open mind. I feel the proposal I have made stands on it's own merits.

As far as I am aware they have. However, you are certainly correct in that it would be good to hear from others on this subject.
 
Also your comment " The fact that you continue not to answer these real issues does not do this issue any good "  ... Other than a decent use case requirement, which is well justified, I feel that I have answered ALL your questions ..
With the last 2 emails you have certainly begun to answer those questions. And for that I'm grateful.
now if you accept them or not is a different matter ... One could also say that I was warned your resistance was to be expected for many reasons .. and no doubt from the same sources you refer to. I will naturally let these sources speak for themselves rather than use them as a justification for my position.
We (HP) are not in a position that having Oracles support on BTP is so important that we will bend-over backwards to accomodate all isues you may say you require. That's not the way this committee has worked in the past and just because we are close to finishing I don't think we should change. All I am asking for is a good use case and a strong reason for why this should be added *now*. If you read back through all of the emails I have sent on this subject you will see that I have never said we should not discuss this or that it shouldn't be added; only that it should be discussed *in detail* and deferred to post 1.0 because there is a lot more required than just state serialisation. Not having this in the 1.0 specification will not affect its take-up IMO, but having it in in a potentially broken form may make it harder to correct later (note, I am *not* saying that the XML we've seen is broken or anything, only that if this is rushed through we run the risk of missing important things that may be required to accomplish what you want.) This all seems reasonable to me.

[ Mark I think you are in isolation here. First off, I am not asking anyone to bend over backwards ( ooh eerr ) .. and if anyone is under the illusion that I am they are mistaken. You have missed the core caveat that is in this proposal .. it is OPTIONAL .. I do indeed want this in the spec, as I think it addresses a major interop problem and thus is attractive to our collective customers.

Now if I instisted that every vendor HAD to implement it - then that would be unreasonable, however I am not.

Yes, Oracle was late to the party, but at least we are here. This to the best of my knowledge is the only major issue that Oracle has. Step in my shoes Mark - I am asking Oracle to bend over backwards to support this spec. And the proposal I put in has value and I am not dictating to anyone.

This is a version 1 - ticket item. I am not going to drop this one Mark, I feel it is to important ]
 
 
 
 

And .. " I know that we are all busy with other things" .. as I mentioned to the group - I am at the whim of Oracle's 4th Quarter and at the scheduling of the BTP calls ... I do my best - period. I am truly sorry that I can not make HP's FTF, however I have noted that we are both presenting at NextWare (May 20-23) yourself on "transactions in a web services model" and I on "GRID infrastructure" so hopefully we can finally meet F2F.
I look forward to it.
Anyway, keep it professional and not personal  .. we all want the same thing, a BTP that is valuable.
I hope so too. 
[ it is a fact ]
 Mark.
Geoff.
