DDLm based dictionaries allow specifying alias data names for data items (i. e. _diffrn.special_details has two aliases -- _diffrn_special_details and _diffrn.details). I was wondering if there are any official IUCr guidelines how the CIF file should be interpreted if several of these values are present in the same data block. Does it become an invalid file (following the logic that a data name can only appear once in a file)?
