Have read this in 
http://www.ietf.org/internet-drafts/draft-ietf-openpgp-rfc2440bis-06.txt:
....
Names in the user name space consist of a UTF-8 string tag followed
by "@" followed by a DNS domain name. Note that the tag MUST NOT
contain an "@" character. For example, the "sample" tag used by
Example Corporation could be "sample@example.com".

Names in a user space are owned and controlled by the owners of that
domain. Obviously, it's of bad form to create a new name in a DNS
space that you don't own.

Since the user name space is in the form of an email address,
implementers MAY wish to arrange for that address to reach a person
who can be consulted about the use of the named tag.  Note that due
to UTF-8 encoding, not all valid user space name tags are valid
email addresses. 
....

for my understanding: the name@domain syntax has something to do with
the UTF-8 encoding or name resolution? Don't understand this
section very well.
And what would you say is the best or general form of the 'name' part of
the notation string for a private user? The e-mail address of the
person, who is the holder or creator of the notation or in conjunction
with a sig or cert policy, the holder/creator of the policy?


Ciao
Kai
