But be aware that pairs with names of non-user namespaces are not necessarily
portable between operating systems and not even between filesystems.
I.e. only those which begin with "user.", like "user.x" or "user.whatever",
can unconditionally be expected to be appropriate on other machines and disks.
Processing of other xattr may need administrator privileges.

Name has to be a 0 terminated string.
Value may be any array of bytes which does not exceed the size of 4095 bytes.

If you restore a backup with xattr from non-user namespaces, then make sure
that the target operating system and filesystem know what these attributes
mean. Possibly you will need administrator privileges to record or restore
such attributes. At recording time, xorriso will try to tolerate missing
privileges and just record what is readable.
But at restore time, missing privileges will cause failure events.
@*
Command -xattr "user" after command -for_backup excludes non-user attributes
from being recorded or restored.
