implements ID3v22FrameBody

Encrypted meta frame

This frame contains one or more encrypted frames. This enables protection of copyrighted information such as pictures and text, that people might want to pay extra for. Since standardisation of such an encryption scheme is beyond this document, all "CRM" frames begin with a terminated string with a URL [URL] containing an email address, or a link to a location where an email adress can be found, that belongs to the organisation responsible for this specific encrypted meta frame.

Questions regarding the encrypted frame should be sent to the indicated email address. If a $00 is found directly after the 'Frame size', the whole frame should be ignored, and preferably be removed. The 'Owner identifier' is then followed by a short content description and explanation as to why it's encrypted. After the 'content/explanation' description, the actual encrypted block follows.

When an ID3v2 decoder encounters a "CRM" frame, it should send the datablock to the 'plugin' with the corresponding 'owner identifier' and expect to receive either a datablock with one or several ID3v2 frames after each other or an error. There may be more than one "CRM" frames in a tag, but only one with the same 'owner identifier'.
