I want to add the value "PROGRAM_STOPPED" for execution events in MTConnectStreams_1.2.
Therefore I added the lines as showed in the attached pics.


After restarting the service I still get this error message:
'PROGRAM_STOPPED' violates enumeration constraint of 'READY INTERRUPTED ACTIVE STOPPED FEED_HOLD UNAVAILABLE'.The element '{urn:mtconnect.org:MTConnectStreams:1.2}Execution' with value 'PROGRAM_STOPPED' failed to parse.'.
How can I solve this problem?
