Topic: Exception specification for overriding functions

Hello:
Forgive me in advance if my question below is inappropriate
or unreasonable in any way.
Which clause of the standard (14882-1998) describes the
restrictions on the exception specifications for an
overriding function in a derived class vis-a-vis the
exception specification for the overridden function in
a base class?
I have scanned through the material dealing with derived
classes (clause 10) of the standard, but have not seen
any mention of the restrictions I am looking for.
If someone could point me in the right direction, I'd be
grateful. Thanks.

P.S.: I'd also like to thank Victor Bazarov and Ron Natalie
for their replies to an earlier post by me.

------------------------------
"[except.spec] 15.4 Exception specifications
3 If a virtual function has an exceptionspecification, all declarations,
including the definition, of any function that overrides that virtual
function in any derived class shall only allow exceptions that are
allowed by the exceptionspecification of the base class virtual function."

Chapter 15 is a separate chapter that deals with exceptions.

Your question is completely on-topic in this group.

15.4/3.

Since this is about exceptions and inheritance, the two obvious places
to look for it are in the inheritance clause (10), as you did, and in
the exception clause (15). I believe the standard avoids backward
references whereever possible, so putting it into 15 seems natural.
HTH,
