controllable?

Yes, you can change enumerator names with the --enumerator-regex option.
For example, if add:

--enumerator-regex //empty_value/ 

when compiling the above schema fragment, I get:

enum value
{
  empty_value,
  busy,
  free
};

For more information on this option, see the NAMING CONVENTION section
in the XSD Compiler Command Line Manual:
