Summary0003633: We need a way to optimize client server interactions with just one service call
Description

There are different scenarios where a client want to invoke only one service on a server and does not want to keep the connection open between infrequent service invocations.

One example is the security key exchange for PubSub.

We need a way to reduce the connection handshake to a minimum necessary for security.

Introduced the concept of session-less service invocation where just a SecureChannel is created and authorization is handled with an AccessToken provided by a Authorization Service.

Added feature in document version OPC UA Part 4 - Services 1.04 Specification Draft 01.docx

Based on our Profiles discussion this text needs to be modified to state that all Services in the list of Service Sets must be supported stateless if they are also supported in a session.

Added the following clarification:
A Server that supports the SessionlessInvoke Service shall limit the execution to the Services of the View Service Set, Attribute Service Set, Method Service Set, NodeManagement Service Set and Query Service Set. All Services of these Service Sets supported by the Server shall also be supported through the SessionlessInvoke Service if this Service is supported.

Made changes in document version OPC UA Part 4 - Services 1.04 Specification Draft 07.docx
