4) Issues

4a) XML Signature and XPointer

Reference to draft of XPointer draft and content that is not in  
XPointer Framework or XPointer Element () Schema  RECs.



4b) Identifiers for XPath 2.0 and XSLT 2.0


put on wiki for

4c) RFC 4514/2253 compatibility


5) XML Signature Draft - confirm status of previous discussion items

5a) XML escaping

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



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

5b) 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?

5c) Add warning?

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

Proposed resolution: Record as best practice item in wiki?

5d) 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)  Interop Test Cases

7a) Please review draft from Juan Carlos and send comments/discussion  
to public email list: 

Clarification from Juan Carlos 

7b) test defined in new C14N11 example (as updated)

7c) Tests for Errata
Agreed at F2F that no tests needed for E02-E05
Test for E01?

7d)  Additional tests discussed at F2F
-  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

7e) Please review process outline on wiki


8) C14N11 - Appendix A
