I have reviewed this document as part of the YANG doctors directorate's 
ongoing effort to review all IETF documents being processed by the IESG.  These 
comments were written with the intent of improving the operational aspects of the 
IETF drafts. Comments that are not addressed in last call may be included in AD reviews 
during the IESG review.  Document editors and WG chairs should treat these comments 
just like any other last call comments. 

This document includes two YANG modules:
- ietf-alarms-x733@2018-11-22.yang
- ietf-alarms@2018-11-22.yang

..and an example YANG module:
- example-xyz-alarms.yang

The modules are valid, well-written, concise and provide ample documentation.

I have pointed out two small spelling errors in descriptive text, but will leave it to the editors to decide on the potential need for submitting a new version.
