Ignoring the actual definition (which is ok, as would be singing domain,
or signer), it seems a bit cumbersome to have pointers from 1.2 -> 2.X
-> 3.5 like that. Can't it all be put in one place? e.g. just define
the thing fully in 3.5, reference that from 1.2 and either omit 2.X or
else make 2.X consist only of a pointer to 3.5.
