Currently, the data dictionary can be created out of the XMI-input file. All elements included in this file will be part of the dictionary (anyway, there is a possibility to [de]select packages). But there is no correspondence between the dictionary and the profile selection you might perform on this input file.
Thus it would be nice to have the possibility to create a dictionary, which is in line with the selection, i.e. only selected elements will appear in the dictionary. Furthermore, also the restriction of multiplicities and enumerations should be considered (i.e. only the customized multiplicities should appear and literals not selected should not appear in the dictionary).
I suppose that this request is a bigger one, because it seems like these two features (data dictionary and selection) are strictly devided right now in the Tool. But I think there is a need for it....
