OK, since you asked, it appears that bit field information for the 
fuses is being duplicated in the iox*.h files.  For example, in 
iox16a4.h the fuse bits are first defined with macros like this:

#define NVM_FUSES_BODLVL1_bm  (1<<1)

Then later a similar, but inverted version is defined:

#define FUSE_BODLVL1  (unsigned char)~_BV(1))

If both of these are automatically derived from the XML file, then I 
suppose there's no problem.  But if one of them is added by hand, then 
it seems that the hand added macro should be defined in terms of the 
other, automatically derived one.

Also, what is the origin of the fuse default values?  I'm not certain 
they are correct for the devices I'm working with.
