Hi developers, I'd like to discuss the specification of namespace. According to the specification, each dot separated portion of a namespace should be [a-zA-Z_]][a-zA-Z0-9_]*. https://avro.apache.org/docs/1.11.1/specification/#names
But the actual implementations of some language bindings don't follow the specification, and accept any characters. Especially, the Java binding generates namespaces which contain "$" for inner classes generated by protobuf. So, should we need to review the namespace specification? Thanks, Kousuke
