FreeBSD and Linux implement something different also called extended attributes.
There should be a possibility to map from FreeBSD/Linux to Solaris.

See above... Since the extended attributes appeared on a Solaris ( 8 update???),
I was looking for a way to map simple exteneded attribute implementation as 
those on Mac OS, FreeBSD and Linux to the more general implementation on 
Solaris.

Before we start defining the first offocial functionality for this Sun feature, 
we should define a mapping for Mac OS, FreeBSD and Linux. It may make sense, to 
define a sub directory for the attribute directory for keeping old versions
of a file.
