28   * Returns the list of tModel keys possessing the keyedReferences in the passed identifier bag.
29   * Output is restricted by list of tModel keys passed in.  If null, all tModels are searched.

34   * tModelList contains tModelInfo elements whose associated tModels match any of the identifiers passed (logical OR by default). 
35   * Specifying the appropriate findQualifiers can override this behavior."
