[ID3 Dev] Implementation question

[Andy Kernahan]

Hi Brian,

I use a factory which creates frames based on the frame ID.

Users can register a new frame type by specifying the frame ID and a
delegate. The delegate is responsible for returning an instance of a
ID3Frame derived type. Derived types must override the Parse method.

Unknown frames are parsed by an ID3BinaryFrame which simply reads the frame
data into an array.

Hope this helps,

Andy.
