/**
 * <p>
 * A request target is the base entity that is the subject of a request. Different types of request
 * have different request targets. For instance a request for a bookmarkable page differs from a
 * request for a link on a previously rendered page, which in turn differs from a request for a
 * shared resource.
 * </p>
 * <p>
 * It is very important (for mounting) that implementations implement
 * {@link java.lang.Object#equals(java.lang.Object)} and {@link java.lang.Object#hashCode()} in a
 * consistent way.
 * </p>
 * Typically, implementations of IRequestTarget are not meant to be used more than once.
