Building Schema from Existing XFM files.

Is it possible to generate the feature definitions from an existing XFM DGN?

 If I import a MapInfo TAB into a DGN, it will generate the XFM attributes.  But can I import these features (either from the DGN or MapInfo TAB file) into the Geospatial Administrator to simplify the generation of the features (and simplify changing products).
