Yeah, that'll still work.  The point here is that domain_in has to be
passed d3's type OID to start with.  If we have a stack of nested
domains over an array type, they'll all have typelem equal to the array
element type (so that they can be subscripted the same as the base type
could be).  I think you're confusing typelem with typbasetype ...
