4)  Interop planning

4a) Does the WG agree to an open interop, allowing non-WG  
participants in interop?

4b) WG volunteers to assemble test cases?

4c) Please respond to questionnaire when available (extend deadline?)

5) XML Signature Draft

5a) Accept current editors draft, with additional changes?

- reference to RFC2253 updated to RFC4515
- "should" to "MAY" at end of 4.4.4
- conversion of last bullet to additional text, since not  
augmentation of encoding rules 

Comment from Konrad 

s/the string encoding rules in section 2.4/the character escaping  
rules in section 2.4/

Verify that changing from RFC 2253 to RFC 4514 does not introduce any  


Note: WG members can live with:
Defer removal of \20 rule to next version of Signature, summarize  
issue in best practices document?

5b) XML escaping

Angle brackets, ampersand, can cause XML to be ill-formed.



Proposed Resolution: Agree to close this issue with no change?

5c) encoding leading space, forgotten? Or remove requirement to  
escape trailing space?


Need to add to bullet list in section 4.4.4. (see agenda item 7a)?

or get rid of item for trailing space, which should be insignificant? 
0051.html Konrad

Proposed Resolution: Agree to defer to subsequent work on Signature?

5d) Add warning?

warning similar to that of section 7.2 of RFC 2253: http://

Proposed resolution: Record as best practice item in wiki?

5e) Reversibility of string to DER/BER encoding not guaranteed 
0021.html , Juan Carlos

Issue of reversibility

section 5.2

and proposed approach:
"state a repertoire of attribute short names that all applications  
must know and then strongly
recommend to use the form "dotted oid of the attribute = hex  
representation of the BER/DER encoding of the value" for the rest of  
not so well-known or even privately defined attributes" 
0049.html , Ed Simon
"I agree that XMLSig DName encoding rules should address the last  
paragraph of Section 5.2 in RFC 4514:"

Second point about removing KeyInfo material from DSig out of scope  
for charter and for roadmap?
Update wiki?

Ask IETF for DName canonicalization, drop issue? 
0052.html , Konrad

Proposed Resolution: Record as issue for next version of Signature  
and/or add note to best practice wiki

6) XML Signature: ds:Reference type as URI versus ds:Object Mime Type 
0000.html , Juan-Carlos

7) C14N11

7a) Current status

 From XML Core public list

The C14N 1.1 Candidate Recommendation is published at

Konrad had pointed out some issues with Appendix A at

7b) Appendix A recommendation

Appendix update: Konrad 

includes changes from Juan Carlos.

Review actions:

ACTION-35 Rich Salz

ACTION-36 Juan Carlos Cruellas, 

ACTION-37 Sean Mullen, closed with: 

ACTION-38 Ed Simon

Appendix update: Konrad 

8) Interop Test Case review

    i) Regression tests
Which original test cases to use for C14N11 and XML Signature

    ii) test defined in new C14N11 example (as updated)

    iii) Tests for Errata
	Agreed at F2F that no tests needed for E02-E05
Test for E01?

    iv) Action to review and summarize test for E06, test for base64
    URI?  Test exists but not well-defined?

    v) Additional tests
-  test case for 1.0 as default see if 1.1 by mistake
- test case which checks for correct sig when xml:base is present
- test case which checks for correct sig when xml:id is present
- generate sig over doc subset, must include c14n11 as  final transform
- new generators not rely on default c14n
- conversion NodeSetData to OctetStreamData:
- Generate a signature having a reference with some xpath transform  
selecting NodeSetData
then we add a XSLT transform that clearly needs OctetStreamData.  
Check on verification: if the resulting signature actually made the  
use of c14n 1.1 explicit in the chain of transforms

9) Any other business

10) Adjourn
