Yes, xattrs are the base of the framework, but I was using "interface"
in a very broad way: ACLs and RichACLs are exposing kernel-defined
policies and rules about file permissions to user space (much as say
chmod(2) and the file mode bits). That's why it seems to make some
sense to place those pages with the other pages that describe
kernel-user-spaces interfaces. Plus, they'd now and then get some
man-pages love :-).

I'd be happy to see acl(5) and eventually richacl(7) in man pages, but
it's your call in the end, of course.

Cheers,
