Subject: Re: [security-services] Draft Minutes for SSTC Conference Call, Mar14, 2006

Hi everybody,

first of all, thanks for these detailed minutes.

This is an interesting remark from which I understand that, without 
having some knowledge of the potential errata, one cannot easily produce 
an interoperable implementation of SAML 2.0. Is this correct?

I like this choice of words ;)

In this case, the ITU-T is not really putting their stamp!

I don't think anybody ever said that. Since defects have been 
identified, some ITU-T Members are surprised (I think) that they are not 
solved. One reason is probably that OASIS doesn't have a concept of 
"Technical Corrigendum" (which helps to quickly correct defects).
But let's try to make some progress.

I don't think this is correct. Providing a document conforms to ITU-T 
Rec. A.5, it can be referenced in the normative part of an ITU-T Rec 
(whether it has the status of an OASIS Standard or not).
As far as the potential errata are concerned, the intention has never 
been to reference them in a normative part (because they aren't 
normative on the OASIS side).

I'm a bit concerned by this "non-normative channel". At list, the 
channel has to be official and ITU-T Members have been requesting more 
than once that the communication channel with OASIS be formalized so 
that any defect issued on the ITU-T side is handled by OASIS. Abbie 
promised at the ITU-T WP2/17 meeting in January that the ITU-T SG17 
Chairman would receive a letter from OASIS. I haven't been yet notified 
that such a document was available for the April meeting of ITU-T SG17.

How is a CD stable? What if the SS TC is disbanded? Will a CD stay 
forever on the OASIS website? (I guess yes.)

> Abbie: This could add a significant turnaround time

I understand Abbie's concerned. If we want to go for Consent next month, 
we would need to have this CD ready by mid-April.

Considering that the list of errata is not a normative text and would 
not be referenced in a normative part of the ITU-T Rec., Abbie is correct.
So the question is (sorry it's late in the night here in France and I 
haven't checked on the website!): Is the list of potential errata freely 
accessible on the OASIS website (without requiring a login/password)?
