29			units
30				Summary of all units present in an IEEE 1394 node.
31				Contains space-separated tuples of specifier_id and
32				version of each unit present in the node.  Specifier_id
33				and version are hexadecimal string representations of
34				u24 of the respective unit directory entries.
35				Specifier_id and version within each tuple are separated
36				by a colon.

92				Hexadecimal string representation of an u24.
93	
94			model_name
95				Contents of a respective textual descriptor leaf.
96	
97			specifier_id
98				Hexadecimal string representation of an u24.
99				Mandatory in unit directories according to IEEE 1212.
100	
101			vendor
102				Hexadecimal string representation of an u24.
103				Mandatory in the root directory according to IEEE 1212.
104	
105			vendor_name
106				Contents of a respective textual descriptor leaf.

119	Description:
120			SCSI target port identifier and logical unit identifier of a
121			logical unit of an SBP-2 target.  The identifiers are specified
122			in SAM-2...SAM-4 annex A.  They are persistent and world-wide
123			unique properties the SBP-2 attached target.
124	
125			Read-only attribute, immutable during the target's lifetime.
126			Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
127			Colon-separated hexadecimal string representations of
128				u64 EUI-64 : u24 directory_ID : u16 LUN
129			without 0x prefixes, without whitespace.  The former sbp2 driver
130			(removed in 2.6.37 after being superseded by firewire-sbp2) used
131			a somewhat shorter format which was not as close to SAM.
