Several impurity types are possible.

$known-impurity-types                  required
 impurity-type-name         character  required
 impurity-type-number       integer    required
$end_known-impurity-types              required

Example

 impurity-type-number = 1

 impurity-type-name   = p-type
 impurity-type-number = 2

 impurity-type-name   = trap
 impurity-type-number = 3
