Subject: Zero Information Length for Non-<strong>All</strong>ocatable Space Stream<br />
Date: October 26, 2004; last update February 28, 2005<br />
DCN-5119<br />
Description:<br />
This DCN is meant for the next <strong>UDF</strong> revision after 2.50 and for the <strong>UDF</strong> 2.50 errata.<br />
There is no requirement for the Non-<strong>All</strong>ocatable Space Stream to have an Information<br />
Length value of zero as for the Non-<strong>All</strong>ocatable Space List in <strong>UDF</strong> 1.50 and lower.<br />
It is absurd to assume that there is any relevant data in this stream.<br />
Change:<br />
In 3.3.7.2 at the top of page 90 replace:<br />
… The allocation descriptors shall have allocation type 1 (allocated but not recorded). …<br />
by:<br />
… The allocation descriptors shall have allocation type 1 (allocated but not recorded).<br />
The Information Length in the File Entry of this stream shall be zero; so all allocation<br />
descriptors are in the file tail. …<br />
