I've created bug 6748229 with a link to this thread as this topic could 
easily be forgotten. That is, the normative reference to the IPv6 scoped 
address architecture needs to be updated, the description of the scope 
id as a number identifier could minimally reference 
NetworkInterface#getIndex (and vice versa), and isSiteLocalAddress 
should be re-examined.
