per cases by A9, XBOOLE_0:def 3;

suppose x in {(IC )} ; :: thesis:

then x = IC by TARSKI:def 1;
hence g1 . x = g2 . x by A1, A4, A6; :: thesis:

end;

suppose x in SCM-Data-Loc ; :: thesis:

then x is Int-Location by A10, AMI_2:def 16;
hence g1 . x = g2 . x by A2, A4, A6; :: thesis:

end;

suppose x in SCM+FSA-Data*-Loc ; :: thesis:

then x is FinSeq-Location by Def3;
hence g1 . x = g2 . x by A3, A4, A6; :: thesis:

thus s1 = s2 by A4, A5, A6, A7, A8; :: thesis:
