+ * A store contact is a contact that includes all the fields of
+ * the contact. For this reason it usually contains more data compared
+ * to the corresponding view contact. It can contain all types of fields that
+ * are supported by the its parent store.
+ *
+ * The store contact can be edited if it's not read-only. The client must
+ * first lock the existing contact then edit it and finally commit the changes.
