* Ownership frame.
* <p/>
* <p/>
* The ownership frame might be used as a reminder of a made transaction
* or, if signed, as proof. Note that the "USER" and "TOWN" frames are
* good to use in conjunction with this one. The frame begins, after the
* frame ID, size and encoding fields, with a 'price payed' field. The
* first three characters of this field contains the currency used for
* the transaction, encoded according to ISO-4217 alphabetic
* currency code. Concatenated to this is the actual price payed, as a
* numerical string using "." as the decimal separator. Next is an 8
* character date string (YYYYMMDD) followed by a string with the name
* of the seller as the last field in the frame. There may only be one
* "OWNE" frame in a tag.
