1.7 Versioning and Capability Negotiation
This document covers versioning issues in the following areas:
Security and Authentication Methods: The Service Descriptor neither requires nor provides any security or authentication methods. The OOB Connector service and Session Factory service contain specific embedded key exchange algorithms that can be used by higher-level protocols to provide a level of security for continuing communication over an OOB channel. However, the specific algorithms are attached to specific versions of the Session Factory service; there is not a more granular means of negotiating algorithms.
Capability Negotiation: This protocol performs explicit capability negotiation by using the Service Descriptor structure (section 2.2.9).
