Sub UserProc;
Var
    Mb: Imetabase;

    Facts: IMetaDictionary;
    Hierarchy: IMetaHierarchy;
    Atts: IMetaAttributes;
    AttsSet: IMetaAttributesSet;
Begin
    Mb := MetabaseClass.Active;
    Rubr := MB.ItemById("OBJ_FC").Edit As IRubricator;
    Facts := Rubr.Facts;
    Atts := Facts.Attributes;
    AttsSet := Atts.CreateSubset("REV;DL", SubsetOperation.Select_);
