464  * 2. If the property is of type DI_PROP_TYPE_UNKNOWN the following steps
465  *    are carried out.
466  *    a. If the value of the property is consistent with a string property,
467  *       the type of the property is DI_PROP_TYPE_STRING.
468  *    b. Otherwise, if the value of the property is consistent with an integer

470  *    c. Otherwise, the property type is treated as alien to prtconf.
471  * 3. If the property type is alien to prtconf, then the property value is
472  *    read by the appropriate routine for untyped properties and the following
473  *    steps are carried out.
474  *    a. If the length that the property routine returned is zero, the
475  *       property is of type DI_PROP_TYPE_BOOLEAN.
476  *    b. Otherwise, if the length that the property routine returned is
477  *       positive, then the property value is treated as raw data of type
478  *       DI_PROP_TYPE_UNKNOWN.
479  *    c. Otherwise, if the length that the property routine returned is
