how to setup a comment block delete with sidki's config

[susa]

using latest from sidki's config

what would be the simplest way to setup a comment block to remove all code

<!-- START HEADER -->
...get rid of all of this...
<!-- END HEADER -->

already tried exceptions-u.ptxt with the url address and
$SET(sComment=§<START HEADER§>/END HEADER)

that did not work
