An important question for C is do AA and BB interact, and if C is working on OWL DL, what constraints are placed on AA and BB. While there are some plausible unfortunate interactions in OWL 1.0 DL, these are to do with interactions over vocabulary items. In the datatype groups work of Pan and Horrocks, the mergeability of datatype groups is weak, and so problems in this area are expected. Jeremy
