 /// The initial support for WAV files mapped a legacy ID3 audio copyright
 /// into a new xmpDM:copyright property. This is special case code to migrate
 /// that into dc:rights['x-default']. The rules:
 /// <pre>
 /// 1. If there is no dc:rights array, or an empty array -
 /// Create one with dc:rights['x-default'] set from double linefeed and xmpDM:copyright.
 /// 2. If there is a dc:rights array but it has no x-default item -
 /// Create an x-default item as a copy of the first item then apply rule #3.
 /// 3. If there is a dc:rights array with an x-default item,
 /// Look for a double linefeed in the value.
 /// A. If no double linefeed, compare the x-default value to the xmpDM:copyright value.
 /// A1. If they match then leave the x-default value alone.
 /// A2. Otherwise, append a double linefeed and
 /// the xmpDM:copyright value to the x-default value.
 /// B. If there is a double linefeed, compare the trailing text to the xmpDM:copyright value.
 /// B1. If they match then leave the x-default value alone.
 /// B2. Otherwise, replace the trailing x-default text with the xmpDM:copyright value.
 /// 4. In all cases, delete the xmpDM:copyright property.
