Validator Configuration File Format¶

You can set up a Validator via a configuration file.
Next, we will show you how to write a configuration file.

The configuration file consists of rules that will be used in validation.

    }
  }
}
rule
{
  for data
  name "Testbed Validation Rule"
  type hierarchical
  trust-anchor
  {
    type file
    file-name "testbed-trust-anchor.cert"

Each rule must have
