It is not so simple. Some background:

Label is stored as UDF Logical Volume Identifier (--lvid) which has above
restrictions. But due to compatibility reasons with Linux systems with older
blkid library/binaries, it is needed to store label also into UDF Volume
Identifier (--vid) which has restriction of 30 resp. 15 characters (again 15
only if label contains at least one Unicode codepoint above U+FF). Moreover
mkudffs prior to version 1.1 is able to process --lvid and --vid params which
contains only ASCII characters. Other non-ASCII character cause creating
damaged file system.

Maybe I should restrict it to 63 for now and refactor later? 63 is not that
little, should be enough for most use cases. Then we can extend API to check a
particular label and not just length.

--- Comment #1 from Pali Rohár  ---
Note that incorrect MBR means that filesystem is not detected by Windows
systems which is a big problem as choice for UDF is multiplatform support.
