/**
 * Private frame.
 * <p/>
 * <p/>
 * This frame is used to contain information from a software producer
 * that its program uses and does not fit into the other frames. The
 * frame consists of an 'Owner identifier' string and the binary data.
 * The 'Owner identifier' is a null-terminated string with a URL
 * containing an email address, or a link to a location where an email
 * address can be found, that belongs to the organisation responsible
 * for the frame. Questions regarding the frame should be sent to the
 * indicated email address. The tag may contain more than one "PRIV"
 * frame but only with different contents. It is recommended to keep the
 * number of "PRIV" frames as low as possible.
