CORBA26 — CCM: Meaning of "exposed" scopes unclear.

ccm/01-08-04 says

"When a name scope is imported, the names of the enclosing scopes in
the fully-qualified pathname of the enclosing scope are exposed within
the context of the importing specification, but their contents are not
imported. An importing specification may not re-define or re-open a
name scope which has been exposed (but not imported) by an import
statement."

Now consider the following "well-defined set of IDL specs":

module X {
module Y {
module Z{};
};
};

and the following import statement

import X::Y;

Now, it appears that this declaration would make it ill-formed to
specify

module X{
interface another_interface{};
};

since "X" is an exposed scope. That appears to be inconsistent, since
clearly, reopening "X" is allowed without the import statement.
