The Eqonomize! accounting file format (EQZ)

The file is an xml file encoded in UTF-8 with doctype EqonomizeDoc.
It should begin with
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE EqonomizeDoc>

The top element is EqonomizeDoc with attributes version (Eqonomize! version), revision (integer, last revision of file), 
and lastid (64-bit unsigned integer, the highest id in the file).

Subelements:

budget_period
currency
category
account
security
schedule
transaction

Schedules and transactions should be listed last.
