 check that every cnf defined type,hffield,rename,... has been referenced
 at least once and if not,   abort with an error

 need to distinguish between NTTIME (absolute time) and relative time

 prune_xxx should only act inside of '[' ']'

 add support for bool8,16,32,64 with tfs strings

 add the remaining array type  (uvarray)

 add code to verify that union tag length is correct
