<fjh> ISSUE-191?

<trackbot> ISSUE-191 -- XML Signature 1.1 and XML Encryption 1.1 use different URIs for sha384. -- OPEN

<trackbot> http://www.w3.org/2008/xmlsec/track/issues/191

<fjh> http://www.w3.org/2001/04/xmlenc#sha384 (in XML Signature 1.1)

<fjh> http://www.w3.org/2001/04/xmldsig-more#sha384 (in XML Encryption 1.1)

<scantor> sorry, VOIP client

don't understand

<Cynthia> Can't hear you either

<scantor> I'm saying people are using the old strings

<scantor> but why was the RFC allowed to expire?

<scantor> I think we have to use the old strings

<fjh> proposed RESOLUTION: use http://www.w3.org/2001/04/xmldsig-more#sha384 for backward compatibility

<scantor> are any other algs affected?

<scantor> I mean other algs

<scantor> SHA256, etc

<scantor> probably need to review that, by looking at anything defined in the RFC

<scantor> double checking, but I believe those are defined in the Apache C++ lib

<scantor> (the "more" URIs)

RESOLUTION: use http://www.w3.org/2001/04/xmldsig-more#sha384 for backward compatibility

<fjh> ACTION: fjh to review sha384 with tlr, re cross-ref, sig [recorded in http://www.w3.org/2010/03/09-xmlsec-minutes.html#action01]

<trackbot> Created ACTION-541 - Review sha384 with tlr, re cross-ref, sig [on Frederick Hirsch - due 2010-03-16].

<fjh> issue-192?

<trackbot> ISSUE-192 -- Namespaces for DerivedKey and pbkdf2 outside of xenc11 namespace -- OPEN

<trackbot> http://www.w3.org/2008/xmlsec/track/issues/192

<fjh> use namespace http://www.w3.org/2009/xmlenc11

<fjh> RESOLUTION: resolve ISSUE-192 as Thomas proposed, using enc11 namespace

Questions related to RNG Schema

<fjh> http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0046.html

<scantor> the one comment I had on the RNG stuff was that the explosion of combinations in an attempt to constrain everything may create more errors

<scantor> yes, that's what concerns me

<scantor> I don't read RNG, it's more of a general comment

<scantor> they're non-normative, so I guess it's moot, just stating a viewpoint

<scantor> (I think it is helping with spec review, separate issue)

<fjh> http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0049.html

<fjh> ECKeyValue, http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0050.html

<fjh> issue: Is "the ECPublicKey element" in Encryption 1.1 and Signature 1.1

<trackbot> Created ISSUE-193 - Is "the ECPublicKey element" in Encryption 1.1 and Signature 1.1 ; please complete additional details at http://www.w3.org/2008/xmlsec/track/issues/193/edit .

<fjh> actually the ECKeyValue element?

<fjh> http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0051.html

<fjh> http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0053.html

<fjh> XML Encryption uses <any namespace="##other"> but

<fjh> XML Encryption 1.1 uses <any namespace="##any">.

<fjh> Is this intentional? Do you really want to allow elements

<fjh> of the namespace http://www.w3.org/2009/xmlenc11#?

<scantor> but he's saying it changed, right?

<fjh> believe the answer is yes, intentional, cannot change older schemas

<scantor> why would we have changed it from 1.0 to 1.1?

<scantor> I haven't looked to see if he's right, but that sounds like a bug

<fjh> need to check where specifically this is, is it new, or a change

<scantor> sure, just capture the links for me

<fjh> ACTION: scott to check on issue related to other and any in XML Enc, see http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0053.html [recorded in http://www.w3.org/2010/03/09-xmlsec-minutes.html#action02]

<trackbot> Created ACTION-542 - Check on issue related to other and any in XML Enc, see http://lists.w3.org/Archives/Public/public-xmlsec/2010Mar/0053.html [on Scott Cantor - due 2010-03-16].

TPAC F2F Scheduling

no meeting in june

<fjh> proposed RESOLUTION: Plan tentatively for F2F at TPAC, Mon-Tue, 1-2

<fjh> November

<fjh> http://lists.w3.org/Archives/Member/member-xmlsec/2010Mar/0008.html

<Cynthia> I have no issues with the dates

RESOLUTION: Plan tentatively for F2F at TPAC, Mon-Tue, 1-2 November.

<scantor> yes

Canonical XML 2.0 and XML Signature 2.0

<fjh> ISSUE-43?

<trackbot> ISSUE-43 -- Improvements to XML Signature schema -- OPEN

<trackbot> http://www.w3.org/2008/xmlsec/track/issues/43

usiie-435?

<scantor> I added various notes to the issue to bring it up to date

issue-43?

<trackbot> ISSUE-43 -- Improvements to XML Signature schema -- OPEN

<trackbot> http://www.w3.org/2008/xmlsec/track/issues/43

<scantor> I noted a couple of possible outstanding concerns we might look at

<fjh> The problem with mixed content models really can't be fixed at this point, but we could choose to include normative "SHOULD NOT" language around some of the elements.

<fjh> Finally, the X509IssuerSerial problem is severe enough that we might choose to address it. We could do so by non-normatively suggesting that implementations relying on schema validation use a modified schema that re-types the serial number as a string, or we could define a new child element in place of the original. It seems like for most implementations the modified schema approach would be sufficient and cause the least trouble. [Scott Cantor]

<scantor> probably, yeah

<scantor> sure

<fjh> ACTION: scantor to make proposals for the last two points noted in ISSUE-43 comments [recorded in http://www.w3.org/2010/03/09-xmlsec-minutes.html#action03]

<trackbot> Created ACTION-543 - Make proposals for the last two points noted in ISSUE-43 comments [on Scott Cantor - due 2010-03-16].

ISSUE-162?

<trackbot> ISSUE-162 -- Will reliable determination of Object elent type and encoding be possible under 2.0 Transform -- OPEN

<trackbot> http://www.w3.org/2008/xmlsec/track/issues/162

<fjh> need to find use case relevant to issue-162, then determine how it works or not with 2.0

<fjh> ACTION: pratik to review ISSUE-162 [recorded in http://www.w3.org/2010/03/09-xmlsec-minutes.html#action04]

<trackbot> Created ACTION-544 - Review ISSUE-162 [on Pratik Datta - due 2010-03-16].

<Cynthia> Any status on the RIM IPR?

<fjh> Efforts are still underway, no new news to report now.
