I coded

  <title abbrev="UPS management protocol">Uninterruptible Power Supply (UPS) Management Protocol
                                     <br>Commands and Responses</title>

but when I attempted to submit this using https://datatracker.ietf.org/submit/ I 
received:

  Meta-data from the submission
  ...
  Title 	Uninterruptible Power Supply (UPS) Management Protocol

The text after the <br> has disappeared.  Is this what should happen?  Roger
