-- The namespace is part of the name "user.xxx.yy". Four predefined spaces:
- security, system, trusted, user. So permissions depend on the name prefix.
- The system namespace is used for implementing acls
-
-- get() can get size by passing buffer of size 0
-
-- The flags to "set" are XATTR_CREATE or XATTR_REPLACE. Default 0 means
- create or replace as appropriate.

- - position is only used with the resource fork, else set to 0
- - names are UTF-8. Max size
- - get with size 0 returns actual size.
- - options: XATTR_NOFOLLOW (all), XATTR_CREATE/XATTR_REPLACE (setxattr()
- not set->either)

-http://arstechnica.com/reviews/os/macosx-10-4.ars/7:
- Apple recommends the use of a reverse-DNS naming scheme (e.g.,
- com.apple.itunes.artist), but with the dots replaced with underscores
- in order to avoid conflicting with the namespace convention used by
- Cocoa's key/value coding system.
- - Max name size 128 ?
-
-There are apparently no predefined namespaces and no restrictions on names
