+ * This class is used to manipulate and access the <components>
+ * field of an IIOP profile (and other GIOP profiles).
+ * The definition for that field is simply a sequence of the
+ * following structures:
+ * typedef unsigned long ComponentId;
+ * struct TaggedComponent {
+ * ComponentId     tag;
+ * sequence<octet> component_data;
+ * };
+ * the real motivation is to minimize the marshaling and
+ * demarshaling of the <component_data> field for certain critical
+ * components.
