+<h3 id="osgi.service-bundle">1. Bundle org.eclipse.osgi.services</h3>
+
+The bundle <code>org.eclipse.osgi.services</code> is deprecated for removal.
+Its content has already been replaced by the official OSGi bundles published to Maven-Central and it only reexports these <code>org.osgi.service.*</code> bundles.
+<p>
+Consumers are encouraged to replace their requirements on the bundle <code>org.eclipse.osgi.services</code> by imports of the used <code>org.osgi.service.*</code> packages already now.
+This allows the OSGi runtime to choose any suitable provider of the package that is available. 
+</p>
