They would have done better if they had
typedef struct _ID3Tag ID3Tag
It's clearly not the real type, so why on earth they pretend it's complete...

Given it's not the real type, it can't be a struct, because it can't be
allocated on the stack. You were already told the correct solution -- you
even quoted it below.

Yes, that's the right solution.
Compact class is something, that is allocated on the heap and passed by
pointer (while struct is allocated on stack and passed by value) but unlike
normal classes does not support reference-counting.

That is a correct guess. It would be
[Compact]
[CCode (cname = "ID3Tag", free_function = "IR3Tag_Delete")]
public class Tag { ...
