Well, nothing if we admit that the range would be large enough to don't 
need validation. But

   checked::serial_date dt = may/11/year(2013);

would be the syntax to build a checked serial date converted from a 
unchecked calendar date, and the validation would be done on the 
conversion.

What do you think to using namespaces instead of prefixes?
This will allow to have checked and unchecked unit specifiers as well.

   using chrono::checked;
   serial_date dt = may/11/year(2013);

   using chrono::unchecked;
   serial_date dt = may/11/year(2013);

Just an idea.

Best,
Vicente
