Hi, 
	mmCIF should be able to handle crystal structures analysed by MAD.
MAD means that data of one crystal are collected at different wavelengths and
so several data sets are given.  Therefore, category _diffrn_radiation should
provide a wavelength ID which is linked to category _reflns.

Example:

loop_
_diffrn_radiation.entry_id 
_diffrn_radiation.wavelength_id
_diffrn_radiation.wavelength   

ZDFB51 1 0.9323 
ZDFB51 2 0.9192 
ZDFB51 3 0.9185 
ZDFB51 4 0.8983 

loop_
_reflns.entry_id   
_reflns.wavelength_id
_reflns.number_obs  
_reflns.number_all   

ZDFB51  1  3028 11370
ZDFB51  2  3052 11598
ZDFB51  3  3054 11572
ZDFB51  4  3056 11653
