> If I parse a protocol {{p}} using {{avro.protocol.parse}}, which defines {{"namespace": "ns"}} and then retrieve a child schema {{s}} from the protocol's {{proto.types}} (or {{proto.types_dict}}), then {{s}} does not have its namespace set (to {{ns}}), even if {{p}} has a namespace.
> This is particularly problematic if I'm using {{s}} to write out an avro file intended to be read by a specific-type reader, because the file header will claim to be objects of type {{s}} (not {{ns.s}}, as expected).
> I've attached two patches: one that makes sure that the {{namespace}} property of protocol types is set to the default namespace of the protocol when not otherwise set.
> The second patch ensures that the {{namespace}} is *not* rendered into JSON when a default protocol specifies the right value already.
