[Zope3-Users] principal without dot

[Florian Lindner]

Hello,
this is the entry from principals.zcml created by mkzopeinstance (a bit 
modified):

  <principal
    id="something.Florian"
    title="Manager"
    login="florian"
    password_manager="Plain Text"
    password="123"
    />

but can I set a id that does not contain a dot?
I ask because I display DC creator metadata on a page and something like 
Florian just looks better than something.Florian.

Thanks,

Florian
