Class ID3_Frame_LINK
The Linked information frame is used to keep information duplication
as low as possible by linking information from another ID3v2 tag that might reside in another audio file or alone in a binary file. It is recommended that this method is only used when the files are stored on a CD-ROM or other circumstances when the risk of file separation is low.
Data should be retrieved from the first tag found in the file to which this link points. There may be more than one LINK frame in a tag, but only one with the same contents.
A linked frame is to be considered as part of the tag and has the same restrictions as if it was a physical part of the tag (i.e. only one ID3_Frame_RVRB frame allowed, whether it's linked or not).
Frames that may be linked and need no additional data are ID3_Frame_ASPI, ID3_Frame_ETCO, ID3_Frame_EQU2, ID3_Frame_MCDI, ID3_Frame_MLLT, ID3_Frame_OWNE, ID3_Frame_RVA2, ID3_Frame_RVRB, ID3_Frame_SYTC, the text information frames (ie frames descendats of ID3_Frame_AbstractText) and the URL link frames (ie frames descendants of ID3_Frame_AbstractLink).
The ID3_Frame_AENC, ID3_Frame_APIC, ID3_Frame_GEOB and ID3_Frame_TXXX frames may be linked with the content descriptor as additional ID data.
The ID3_Frame_USER frame may be linked with the language field as additional ID data.
The ID3_Frame_PRIV frame may be linked with the owner identifier as additional ID data.
The ID3_Frame_COMM, ID3_Frame_SYLT and ID3_Frame_USLT frames may be linked with three bytes of language descriptor directly followed by a content descriptor as additional ID data.
