If you describe a SSI as follows

  <!--#include virtual="mb/nerimb4.cgi?mode=ssi&line=7" -->

  or

  <!--#exec cgi="cgi-bin/mbssi.cgi -->

  *)Directory name needs to be set to match your environment.

Then, it will display as follows

[an error occurred while processing this directive]

You can decorate whatever you want, like using table as follows
[an error occurred while processing this directive]

If you save the script as mbssi.cgi, the display line number is specified in the admin setup page.
