429  * 2. If the property is of type DI_PROP_TYPE_UNKNOWN the following steps
430  *    are carried out.
431  *    a. If the value of the property is consistent with a string property,
432  *       the type of the property is DI_PROP_TYPE_STRING.
433  *    b. Otherwise, if the value of the property is consistent with an integer

435  *    c. Otherwise, the property type is treated as alien to prtconf.
436  * 3. If the property type is alien to prtconf, then the property value is
437  *    read by the appropriate routine for untyped properties and the following
438  *    steps are carried out.
439  *    a. If the length that the property routine returned is zero, the
440  *       property is of type DI_PROP_TYPE_BOOLEAN.
441  *    b. Otherwise, if the length that the property routine returned is
442  *       positive, then the property value is treated as raw data of type
443  *       DI_PROP_TYPE_UNKNOWN.
444  *    c. Otherwise, if the length that the property routine returned is
445  *       negative, then there is some internal inconsistency and this is
