Hello,
You should be able to use dots in the NAME but not in the ALIAS. However, as you stated we should detect this and fix it for you and we do not. The alias gets translated directly to URL and in URL's a dot signifies the end of a domain and the beginning of a domain extension (.com, .net, .gr, .ca etc).
Maybe we could substitute a dot for a hyphen (911-F-3-A-R).
