Priority will assign a priority to the message (with 1 being the highest and
10 being the lowest). A message of higher priority will replace a message
of lower priority on the Window Banner or Marquee.
You can choose to Show or Suppress extra blanks in your message
depending on how you want to format your message.
Multiple messages may be enabled or disabled for SDS instructions only
(for example, multiple messages may be generated for a single SDS fault).
