 /**
  * {@link PropertySet} that combines properties exposed from multiple
  * {@link PropertySet}s into one.
  *
  * <p>
  * This implementation allows one {@link PropertySet} to assemble
  * all properties exposed from other "satellite" {@link PropertySet}s.
  * (A satellite may itself be a {@link DistributedPropertySet}, so
  * in general this can form a tree.)
  *
  * <p>
  * This is useful for JAX-WS because the properties we expose to the application
  * are contributed by different pieces, and therefore we'd like each of them
  * to have a separate {@link PropertySet} implementation that backs up
  * the properties. For example, this allows FastInfoset to expose its
  * set of properties to {@link RequestContext} by using a strongly-typed fields.
  *
  * <p>
  * This is also useful for a client-side transport to expose a bunch of properties
  * into {@link ResponseContext}. It simply needs to create a {@link PropertySet}
  * object with methods for each property it wants to expose, and then add that
  * {@link PropertySet} to {@link Packet}. This allows property values to be
  * lazily computed (when actually asked by users), thus improving the performance
  * of the typical case where property values are not asked.
  *
  * <p>
  * A similar benefit applies on the server-side, for a transport to expose
  * a bunch of properties to {@link WebServiceContext}.
  *
  * <p>
  * To achieve these benefits, access to {@link DistributedPropertySet} is slower
  * compared to {@link PropertySet} (such as get/set), while adding a satellite
  * object is relatively fast.
