   * The reparse point tag defines the type of the reparse point. It also
   * includes several flags, which further describe the reparse point.
!  *
!  * The reparse point tag is an unsigned 32-bit value divided in three parts:
!  *
!  * 1. The least significant 16 bits (i.e. bits 0 to 15) specifiy the type of
!  *    the reparse point.
!  * 2. The 13 bits after this (i.e. bits 16 to 28) are reserved for future use.
!  * 3. The most significant three bits are flags describing the reparse point.
!  *    They are defined as follows:
!  *	bit 29: Name surrogate bit. If set, the filename is an alias for
!  *		another object in the system.
!  * 	bit 30: High-latecny bit. If set, accessing the first byte of data will
!  *		be slow. (E.g. the data is stored on a tape drive.)
!  * 	bit 31: Microsoft bit. If set, the tag is owned by Microsoft. User
!  *		defined tags have to use zero here.
