From the protocol reference: 
%  Names, in this protocol, are ASCII strings. They may contain letters (A-Z and 
%  a-z), numerals (0-9), hyphen ("-"), plus ("+"), slash ("/"), semicolon (";"), 
%  dot ("."), dollar-sign ("$"), and parentheses ("(" and ")"), but they may not 
%  begin with a hyphen. They are terminated by white space (either a 
space char or 
%  end of line). Each name must be at least one character long.
