Proposed resolution (04/01): Change text in 14.5 [except.spec] paragraph 1 from:

An exception-specification shall appear only on a function declarator in a function, pointer, reference or pointer to member declaration or definition.
to:
An exception-specification shall appear only on a function declarator for a function type, pointer to function type, reference to function type, or pointer to member function type that is the top-level type of a declaration or definition, or on such a type appearing as a parameter or return type in a function declarator.

(See also issues 25, 92, and 133.)

In 14.5 [except.spec] paragraph 2:

An exception-specification shall appear only on a function declarator in a function, pointer, reference or pointer to member declaration or definition.
Does that mean in the top-level function declarator, or one at any level? Can one, for example, specify an exception specification on a pointer-to-function parameter of a function?
    void f(int (*pf)(float) throw(A))
Suggested answer: no. The exception specifications are valid only on the top-level function declarators.

However, if exception specifications are made part of a function's type as has been tentatively agreed, they would have to be allowed on any function declaration.

There is already an example of an exception specification for a parameter in the example in 14.5 [except.spec] paragraph 1.
