Attribute parsers are classes that parse xml attribute values, turning them into valid Java expressions.

    if (parser == null) {
      logger.die(this, "No such attribute %s", name);
    }

      return parser.parse(value);
    } catch (UnableToCompleteException e) {
      logger.die(this, "Cannot parse attribute %s", name);
