Description:
DCN-5120
This DCN is for the next UDF revision after UDF 2.50 (UDF 2.60).
As decided in the UDF committee meetings of November and December 2004, the
Minimum UDF Read Revision for all UDF 2.60 media shall be at most #250. This is an
indication to a UDF 2.50 implementation that it can read all UDF 2.60 media.
December 6, 2004 minutes:
“It's suggested that using 0260 instead of 0150 for the revision number used
in example is preferable”.
However, this would not show what the function of this field is, so #0250 is chosen
instead;
Change:
At the end of 2. Basic Restrictions & Requirements (page 10)
add two items:
Minimum UDF Read Revision
The Minimum UDF Read Revision value shall be at
most #0250 for all media with a UDF 2.60 file
system. This indicates that a UDF 2.50
implementation can read all UDF 2.60 media.
Media that do not have a Metadata Partition may
use a value lower than #250.
In 2.2.6.4. replace:
Minimum UDF Read Revision - Shall indicate …
…
… This number shall be stored in binary coded decimal format, for
example #0150 would indicate revision 1.50 of the UDF specification.
by:
Minimum UDF Read Revision - Shall indicate …
…
… This number shall be stored in binary coded decimal format, for example
#0250 would indicate revision 2.50 of the UDF specification.
See further requirements in the Basic Restrictions & Requirements section.
