Besides this I still think the XEP is misleading since it frequently mentions
"d'artagnan at musketeers.lit" as it was an ordinary user (and is) and it leads
a developer (me) to believe that this mapping shall be generally applied.
Also, the motivations behind the XEP as mentioned in its Introduction
uses ordinary user's name (O'Hara and D'Artagnan).

I can see that the XEP is useful in both situations, ordinary users where the
node+domain+resource split is not known beforehand, and where we need
a 1-to-1 mapping, which therefore excludes "@" and/or "/", 
and the handling of non-XMPP addresses, where also the "@" and "/" characters 
need to be escaped.
