[netmod] removing a node from a grouping

[Kent Watsen <[e-mail]>]

Say there is:

  grouping "foo-bar-etc" {
    container-or-leaf "foo" { ... }
    container-or-leaf "bar" { ... }
    ...  // the "etc" ;)
  }

And the goal is to use the grouping sans the "foo" node.
Can a "when" statement that always evaluates to "false"
do it?

  grouping "bar-etc" {
    uses "foo-bar-etc" {
      refine "listen" {
        when "false()";
      }
    }
  }

Any better ideas?

Thanks,
Kent
