+	 * @param properties

+	 *            object must all be <code>String</code> objects. See
+	 *            {@link Constants} for a list of standard service property
+	 *            keys. Changes should not be made to this object after calling

+	 *            called. Caller should, at a minimum, pass an empty
+	 *            dictionary--never null. We add a property to the collection
+	 *            (we modify the caller's object), to record the id of the dsf
+	 *            session associated with the service.
