The Test Definition has changed, therefore this Test Case needs to be updated.

Description and Expected Result of Step 1 needs to be changed. Also introduce a new Test Requirement.

Change Description from:
"Client creates a subscription with default parameters and adds an active monitored item (static writeable value). Client writes a value. Client calls Publish. Client calls SetPublishingMode with PublishingEnabled=false. Client writes a value and calls publish."
to
"Client creates a subscription with default parameters and adds an active monitored item.
Client calls Publish.
Client calls SetPublishingMode with PublishingEnabled=false."

Add Test Requirement:
"Client supports changing PublishingMode"

Change Expected Result from:
"1st publish call yields a data change notification which the client will process. 2nd publish call does not yield a data change notification."
to
"Client continue to call publish."
