<DIV><FONT face=Arial size=2>Dear Express experts,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would like to check the impact of a select type
extension, on the basis of the latest specifications of Express
ed2.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I declare:</FONT></DIV>
<DIV><FONT face=Arial size=2> TYPE t1 = EXTENSIBLE SELECT
(tata);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> TYPE t2 = SELECT BASED ON t1
WITH (toto);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> TYPE t3 = EXTENSIBLE SELECT
BASED ON t1 WITH (titi);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1) is t1 still extensible (as t2 is not
extensible)?</FONT></DIV>
<DIV><FONT face=Arial size=2>2) what is the actual content of t2: is it : (tata,
toto) or (tata, toto, titi)?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(note: modelling of some modules depend on your
answer)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance for your help</FONT></DIV>
