/**
 * JQuery views meta-data.
 * <p/>
 * This meta-data is registered as downstream of {@link JQueryMetadata}. When
 * {@link GvNIXWebJQuery} is added to any Java Controller the
 * {@link JQueryMetadataProvider} receives the notification and propagates it to
 * {@link JQueryMetadata} downstreams, including this meta-data.
 * <p/>
 * When the provider of this meta-data (
 * {@link JQueryJspMetadataListener#get(String)} ) is notified it updates the
 * view related to the Controller in which {@link GvNIXWebJQuery} was added.
 * Note upstream token contains the identifier of the target Java type and the
 * identifier of applied meta-data.
 * <p/>
 * Note this meta-data item neither contains nor composes details of the related
 * Java type because it doesn't create any ITD.
