* An exported package.

* The term exported package refers to a package that has been exported
* from a resolved bundle. This package may or may not be currently wired to
* other bundles.

*
* The information about an exported package provided by this object may change.
* An {@code ExportedPackage} object becomes stale if the package it
* references has been updated or removed as a result of calling
* {@code PackageAdmin.refreshPackages()}.
*
* If this object becomes stale, its {@code getName()} and
* {@code getVersion()} methods continue to return their original values,
* {@code isRemovalPending()} returns {@code true}, and
* {@code getExportingBundle()} and {@code getImportingBundles()}
* return {@code null}.
