+ * @class journal_builder_t
+ *
+ * @brief This custom builder creates an XML-mirrored Ledger journal.
+ *
+ * Rather than simply creating a node_t hierarchy, as xml_builder_t
+ * does, this code creates the associated journal elements referred to
+ * by those nodes, and then refers to those elements via minimalist
+ * "shadow nodes".
+ *
+ * Thus, after building a <transaction> element, the element itself
+ * will have no children, but instead will point to a transaction_t
+ * object.  If later an XPath expression desires to traverse the
+ * <transaction> element, all of the appropriate child nodes will be
+ * constructed on the fly, as if they'd been created in the first
+ * place by a regular xml_builder_t.
