Note that the Linux style is already supported:
setextattr system.md5 `md5 -q /boot/kernel/kernel` /boot/kernel/kernel

I recall implementing it last summer, but reading the man page, it seems
lsextattr was not completed: you need to tell if you want user or
system attributes. system will give you any extattr with name starting
by system, security and trusted. user gives you everythign else.

You can do this:
        setextattr user.mycategory "red bucket" ./foo.txt

Or even, that:
        setextattr whatever.mycategory "red bucket" ./foo.txt
