That does not provide more information :-)

I'm thinking if we can provide UDF revision/version of UDF filesystem to
userspace and looks like ID_FS_VERSION is good candidate for it...
What do you think?
E.g. Linux kernel is able to read UDF filesystem up to revision 2.50 and
has read-write support up to revision 2.01. So for userspace this
information can be useful.
