It depends on the meaning of 'empty' ;)  
If you set an empty value through the standard user interface, the value is 
set to an empty string "", which works without 'optional', but if the value 
has never been set, then url_string property defaults to None (as no 
"default" is set in the property sheet), which requires 'optional' attribute.
