Actually, that's not strictly true.  Pragma Export may
be applied to any entity, including a package, an exception,
a type, etc.  However, support for exporting some of these
kinds of entities is implementation-defined, and from
a practical point of view, not many compilers support
these kinds of exports.

This could be a legitimate interpretation for pragma Export
on a package.  Again, though, pragma Export is not
standardized once you go past the requirements given
in Annex B for particular languages.
