However, this document itself may not be modified in any way, including by removing the copyright notice or references to OASIS, except as needed for the purpose of developing any document or deliverable produced by an OASIS Technical Committee (in which case the rules applicable to copyrights, as set forth in the OASIS IPR Policy, must be followed) or as required to translate it into languages other than English.

OASIS requests that any OASIS Party or any other party that believes it has patent claims that would necessarily be infringed by implementations of this OASIS Committee Specification or OASIS Standard, to notify OASIS TC Administrator and provide an indication of its willingness to grant patent licenses to such patent claims in a manner consistent with the IPR Mode of the OASIS Technical Committee that produced this specification.

OASIS invites any party to contact the OASIS TC Administrator if it is aware of a claim of ownership of any patent claims that would necessarily be infringed by implementations of this specification by a patent holder that is not willing to provide a license to such patent claims in a manner consistent with the IPR Mode of the OASIS Technical Committee that produced this specification. OASIS may include such claims on its website, but disclaims any obligation to do so.

OASIS takes no position regarding the validity or scope of any intellectual property or other rights that might be claimed to pertain to the implementation or use of the technology described in this document or the extent to which any license under such rights might or might not be available; neither does it represent that it has made any effort to identify any such rights. Information on OASIS' procedures with respect to rights in any document or deliverable produced by an OASIS Technical Committee can be found on the OASIS website. Copies of claims of rights made available for publication and any assurances of licenses to be made available, or the result of an attempt made to obtain a general license or permission for the use of such proprietary rights by implementers or users of this OASIS Committee Specification or OASIS Standard, can be obtained from the OASIS TC Administrator. OASIS makes no representation that any information or list of intellectual property rights will at any time be complete, or that any claims in such list are, in fact, Essential Claims.

1      Issues Addressed

The following issues related to WS-SecurityConversation 1.3 as recorded in the [WS-SX Issues] have been addressed in this document.




Clarification of policy usage for derived keys in SC


Change key to crucial in SC


Review normative RFC 2119 language in WS-SecureConversation


Conflict Nonce reuse description in the current WS-SC 1.3


Add conformance statements to new versions of Trust/SC/SP


Update policy references to 1.5 for SC, Trust and SP


Update XML Signature references to refer to XML Signature, Second Edition, update c14n reference in ws-trust


2      Typographical/Editorial Errors

2.1 Normative language capitalization changes

The following changes do not affect the normative meaning of the text, they are only to properly capitalize 2119 terms. The changes listed below document the changes as they appear in the text. There were many instances of the terms OPTIONAL and REQUIRED in the schema exemplar descriptions that appeared un-capitalized that are not captured below but that have also been addressed. All other 2119 terms that remain un-capitalized are used in their English sense.


Line 236

If a token provides multiple keys then specific bindings and profiles MUST describe how to reference the separate keys


Line 356

In order for the security token service to process this request it MUST have prior knowledge for which Web Service the requestor needs a token


Line 612

the requestor is REQUIRED to re-authenticate the original claims in every renewal request


Line 757

Using a common secret, parties MAY define different key derivations to use.


Line 758

In order to keep the keys fresh (prevent providing too much data for analysis), subsequent derivations MAY be used


Line 784

The nonce seed is REQUIRED


Line 802

When a new key is required, a new <wsc:DerivedKeyToken> MAY be passed referencing the previously generated key


Line 843

then a fault such as wsc:UnknownDerivationSource SHOULD be raised.


2.2 Section 1

Removed lines 17 – 19 (to new section 1.8)

Compliant services are NOT REQUIRED to implement everything defined in this specification.  However, if a service implements an aspect of the specification, it MUST comply with the requirements specified (e.g. related "MUST" statements).

3      Normative Errors
